I/O type
Input/Output This is an 8-bit I/O port equivalent to P0. P7 can also function as
I/O for timer A0 to A3, as selected by software. Additional
programming options are: P7
UART2 I/O capabilities, and P7
for the three-phase motor control timer.
Input/Output This is an 8-bit I/O port equivalent to P0. Additional software
selectable secondary functions are: 1) P8
either I/O for Timer A4, as output pins for the three-phase motor
control timer; 2) P8
pins. P8
used as NMI/SD. P8
phase motor control is enabled. Apply a stable "H" to P8
setting the direction register for P8
motor control is enabled, and; 4) P8
for the subclock generation circuit. In this latter case, a quartz
oscillator must be connected between P8

Input/Output This is an 7-bit I/O port equivalent to P0. Additional software
selectable scondary functions are: 1) P9
B0 to B2 input pins; 2) P9
pins; 3) P9
of X
program; 4) P9
module; 5) P9
and; 6) P9
pin version.
Input/Output This is an 8-bit I/O port equivalent to P0. This port can also function
as A/D converter input pins, as selected by software. Furthermore,
