Description
Ground pin
Power supply pins
Crystal OSC input, internal clock input
Crystal OSC input, internal clock output
Pseudo-bidirectional ports for 4-bit parallel I/O. To input data from these ports,
it is necessary to write "1" beforehand.
The port to be selected is specified by the L register. The register contents and
the corresponding specified ports are listed below.
Note: P3, P4, and P5 are internal ports.
Input port for 4-bit parallel input with no latching function.
Input pin to request an interrupt from the external circuit. The input flag is set at
the falling edge of the input signal.
The reset mode starts after "0" is input to the
RESET
pin for more than 2
machine cycles.
The reset signal has priority over all of other signals and performs the following
operations automatically:
(1) Resets all bits of the PC (program counter) to"0".
(2) Sets all bits of the parallel I/O ports (P0.0 to P1.3) to "1"
(3) Resets the internal register (H, L, A
CC
, C, P3, P4, P5).
(4) Resets the skip flag.
(5) Resets all bits of the time base counter (TBC).
(6) Resets the interrupt request flag (IRQF).
(7) Resets the interrupt enable flag (EIF).
(8) Resets the master interrupt enable flag (MEIF).
(9) Sets all bits of the stack pointer (SP) to "1" .
(10) Initializes the segment and common outputs.
(11) Sets all bits of the index register (IDR) to "1".

RESET
Since the
RESET
pin is pulled up to V
DD
by an internal resistor (800 k
W
), it is
possible to achieve power ON reset by connecting it with an external capacitor.
