NOTES ON PROGRAMMING
Processor Status Register
The contents of the processor status register (PS) after a reset are
undefined, except for the interrupt disable flag (I) which is “1.” Af-
ter a reset, initialize flags which affect program execution. In
particular, it is essential to initialize the index X mode (T) and the
decimal mode (D) flags because of their effect on calculations.
Interrupts
The contents of the interrupt request bits do not change immedi-
ately after they have been written. After writing to an interrupt
request register, execute at least one instruction before perform-
ing a BBC or BBS instruction.
Decimal Calculations
To calculate in decimal notation, set the decimal mode flag (D)
to “1”, then execute an ADC or SBC instruction. After executing
an ADC or SBC instruction, execute at least one instruction be-
fore executing a SEC, CLC, or CLD instruction.
In decimal mode, the values of the negative (N), overflow (V),
and zero (Z) flags are invalid.
Timers
If a value n (between 0 and 255) is written to a timer latch, the fre-
quency division ratio is 1/(n+1).
Multiplication and Division Instructions
The index X mode (T) and the decimal mode (D) flags do not af-
fect the MUL and DIV instruction.
The execution of these instructions does not change the con-
tents of the processor status register.
Ports
The contents of the port direction registers cannot be read. The
following cannot be used:
The data transfer instruction (LDA, etc.)
The operation instruction when the index X mode flag (T) is “1”
The addressing mode which uses the value of a direction regis-
ter as an index
The bit-test instruction (BBC or BBS, etc.) to a direction register
The read-modify-write instructions (ROR, CLB, or SEB, etc.) to
a direction register.
Use instructions such as LDM and STA, etc., to set the port direc-
tion registers.
Serial I/O
In serial I/O1 (clock synchronous mode), if the receive side is us-
ing an external clock and it is to output the SRDY1 signal, set the
transmit enable bit, the receive enable bit, and the SRDY1 output
enable bit to “1.”
Serial I/O1 continues to output the final bit from the TXD pin after
transmission is completed.
SOUT2 pin for serial I/O2 goes to high impedance after transmis-
sion is completed.
When an external clock is used as synchronous clock in serial
I/O1 or serial I/O2, write transmission data to the transmit buffer
register or serial I/O2 register while the transfer clock is “H.”
A-D Converter
The comparator uses capacitive coupling amplifier whose charge
will be lost if the clock frequency is too low.
Therefore, make sure that f(XIN) in the middle/high-speed mode is
at least on 500 kHz during an A-D conversion.
Do not execute the STP instruction or the WIT instruction during
an A-D conversion.
Instruction Execution Time
The instruction execution time is obtained by multiplying the fre-
quency of the internal clock
φ by the number of cycles needed to
execute an instruction.
The number of cycles required to execute an instruction is shown
in the list of machine instructions.
The frequency of the internal clock
φ is half of the XIN frequency in
high-speed mode.
NOTES ON USAGE
Handling of Source Pins
In order to avoid a latch-up occurrence, connect a capacitor suit-
able for high frequencies as bypass capacitor between power
source pin (VCC pin) and GND pin (VSS pin) and between power
source pin (VCC pin) and analog power source input pin (AVSS
pin). Besides, connect the capacitor to as close as possible. For
bypass capacitor which should not be located too far from the pins
to be connected, a ceramic capacitor of 0.01
F–0.1F is recom-
mended.
EPROM Version/One Time PROM Version
The CNVss pin is connected to the internal memory circuit block
by a low-ohmic resistance, since it has the multiplexed function to
be a programmable power source pin (VPP pin) as well.
To improve the noise reduction, connect a track between CNVss
pin and Vss pin or Vcc pin with 1 to 10 k
resistance.
The mask ROM version track of CNVss pin has no operational in-
terference even if it is connected to Vss pin or Vcc pin via a
resistor.
Electric Characteristic Differences between
Mask ROM and One Time PROM Version
MCUs
There are differences in electric characteristics, operation margin,
noise immunity, and noise radiation between mask ROM and One
Time PROM version MCUs due to the differences in the manufac-
turing processes.
When manufacturing an application system with One Time PROM
version and then switching to use of the mask ROM version, per-
form sufficient evaluations for the commercial samples of the
mask ROM version.
