M16C/26A Group (M16C/26A, M16C/26T)
Under development Preliminary specification
Specifications in this manual are tentative and subject to change.

Table 1.7. Pin Description(2)
Pin name
Signal name
I/O type
Function
P80~P87
I/O port P8
Input/
This is an 8-bit I/O port equivalent to P6. Additional software-selectable
output
secondary functions are: 1) P80 and P81 can act as either I/O for Timer
A4, or as output pins for the three-phase motor control timer; 2) P82 to
______
P84 can be configured as external INT interrupt pins. P84 can be used for
_______ _____
Timer A Zphase function; 3) P85 can be used as NMI/SD. P85 can not be
used as I/O port while the three-phase motor control is enabled. Apply a
stable "H" to P85 after setting the direction register for P85 to "0" when
the three-phase motor control is enabled, and; 4) P86 and P87 can serve
as I/O pins for the sub-clock generation circuit. In this latter case, a quartz
oscillator must be connented between P86 (XCOUT pin) and P87 (XCIN pin).
P90~P93
I/O port P9
Input/
This is an 4-bit I/O port equivalent to P6. Additional software-selectable
output
secondary functions are: 1) P90 to P92 can act as Timer B0~B2 input
pins, and; 2) P90 to P93 can act as A/D converter input pins.
P90 outputs a no-divide, divide-by-8 or divide-by-32 clock of XIN or a
clock of the same frequency as XCIN as selected by program. P92 to P93
are not available in the 42 pin version.
P100~P107 I/O port P10
Input/
This is an 8-bit I/O port equivalent to P6. This port can also function as
output
A/D converter input pins, as selected by software. Furthermore, P104 to
P107 can also function as input pins for the key input interrupt function.
