Type
FP-80A, CP-84,
Symbol TFP-80C CG-84 I/O Name and Function
I/O ports
P6₇ to P6₀ 28 to 21 40 to 33 I/O Port 6: An 8-bit input/output port with
programmable MOS input pull-ups.
The direction of each bit can be
selected in the port 6 data direction
register (P6DDR).
P7₇ to P7₀ 37 to 30 50 to 43 I
Port 7: An 8-bit input port.
P8₆ to P8₀ 80 to 74 11 to 5
I/O Port 8: A 7-bit input/output port. The
direction of each bit can be selected in
the port 8 data direction register
(P8DDR).
P9₇ to P9₀ 13 to 20 25 to 32 I/O Port 9: An 8-bit input/output port. The
direction of each bit (except for P9₆)
can be selected in the port 9 data
direction register (P9DDR).
Note:
In this chip, except for the S-mask model (single-power-supply specification), the same pin
is used for STBY and FV_PP. When this pin is driven low, a transition is made to hardware
standby mode. This happens not only in the normal operating modes (modes 1, 2, and 3),
but also when programming the flash memory with a PROM writer. When using a PROM
programmer to program dual-power-supply flash memory, therefore, the PROM
programmer specifications should provide for this pin to be held at the V_CC level except
when programming (FV_PP = 12 V).
