PIN DESCRIPTIONS
Symbol
Name and Function
V
CC
V
SS
V
REF
Main supply voltage (5V).
Digital circuit ground (0V).There are multiple V
SS
pins, all of them must be connected.
Reference voltage for the A/D converter (5V).V
REF
is also the supply voltage to the analog
portion of the A/D converter and the logic used to read Port 0. Must be connected for A/D
and Port 0 to function.
ANGND
Reference ground for the A/D converter. Must be held at nominally the same potential as
V
SS
. Connect V
SS
and ANGND at chip to avoid noise problems.
Programmingvoltage. Also timing pin for the return from power down circuit.
V
PP
XTAL1
Input of the oscillator inverter and of the internal clock generator.
XTAL2
Output of the oscillator inverter.
CLKOUT
Output of the internal clock generator. The frequency of CLKOUT is
(/2
the oscillator
frequency. It has a 50% duty cycle.
RESET
Reset input to and open-drain output from the chip. Input low for at least 4 state times to reset
the chip. The subsequent low-to-high transition re-synchronizes CLKOUT and commences a
10-state-time RESETsequence.
BUSWIDTH
Input for buswidth selection. If CCRbit 1 is a one, this pin selects the bus width for the bus
cycle in progress. If BUSWIDTHis a 1, a 16-bit bus cycle occurs. If BUSWIDTHis a 0 an 8-bit
cycle occurs. If CCRbit 1 is a 0, the bus is always an 8-bit bus.
NMI
A positive transition causes a vector through 203EH.
INST
Output high during an external memory read indicates the read is an instruction fetch and
output low indicates a data fetch. INST is valid throughout the bus cycle. INST is activated
only during external memory accesses.
EA
Input for memory select (External Access). EA equal to a TTL-high causes memory accesses
to locations 2000H through 3FFFH to be directed to on-chip ROM/OTPROM. EA equal to a
TTL-low causes accesses to these locations to be directed to off-chip memory.
ALE/ADV
Address Latch Enable or Address Valid output, as selected by CCR.Both pin options provide
a latch to demultiplex the address from the address/data bus. When the pin is ADV, it goes
inactive high at the end of the bus cycle. ALE/ADV is activated only during external memory
accesses.
RD
Read signal output to external memory. RD is activated only during external memory reads.
WR/WRL
Write and Write Low output to external memory, as selected by the CCR.WR will go low for
every external write, while WRL will go low only for external writes where an even byte is
being written. WR/WRL is activated only during external memory writes.
BHE/WRH
Bus High Enable or Write High output to external memory, as selected by the CCR.BHE will
go low for external writes to the high byte of the data bus. WRH will go low for external writes
where an odd byte is being addressed. BHE/WRH is activated only during external memory
writes.
READY
Ready input to lengthen external memory cycles. If the pin is low prior to the falling edge of
CLKOUT,the memory controller goes into a wait mode until the next positive transition in
CLKOUT occurs with READY high. When the external memory is not being used, READY has
no effect. Internal control of the number of wait states inserted into a bus cycle (held not
ready) is available in the CCR.
HSI
Inputs to High Speed Input Unit. Four HSI pins are available: HSI.0,HSI.1,HSI.2 and HSI.3.
Two of them (HSI.2and HSI.3)are shared with the HSO Unit.
HSO
Outputs from High Speed Output Unit. Six HSO pins are available: HSO.0,HSO.1,HSO.2,
HSO.3,HSO.4 and HSO.5.Two of them (HSO.4and HSO.5)are shared with the HSI Unit.
