2.2.5 P60 to P63 (port 6)
mode register 6 (PM6).
P20 to P27 function as an 8-bit input-only port. These pins also function as pins for A/D converter analog input.
The following operation modes can be specified in 1-bit units.
P30 to P33 function as a 4-bit I/O port. These pins also function as pins for external interrupt request input and
The following operation modes can be specified in 1-bit units.
P60 to P63 function as a 4-bit I/O port. P60 to P63 can be set to input port or output port in 1-bit units using port
P60 to P63 are N-ch open-drain pins.
P20 to P27 function as an 8-bit input-only port.
P20 to P27 function as A/D converter analog input pins (ANI0 to ANI7). When using these pins as analog input
pins, see (5) ANI0/P20 to ANI7/P27 in 11.6 Cautions for A/D Converter.
P30 to P33 function as a 4-bit I/O port. P30 to P33 can be set to input or output in 1-bit units using port mode
register 3 (PM3). Use of an on-chip pull-up resistor can be specified by pull-up resistor option register 3 (PU3).
P30 to P33 function as external interrupt request input pins and timer I/O pins.
(a) INTP1 to INTP4
(b) TI51
(c) TO51
Caution In the PD78F0114HD, be sure to pull the P31 pin down after reset to prevent malfunction.
Remark P31/INTP2 and P32/INTP3 of the PD78F0138HD can be used as on-chip debug mode setting pins
These are the external interrupt request input pins for which the valid edge (rising edge, falling edge, or both
rising and falling edges) can be specified.
This is an external count clock input pin to 8-bit timer/event counter 51.
This is a timer output pin.
when the on-chip debug function is used. For details, refer to CHAPTER 24 ON-CHIP DEBUG
