CHAPTER 4 PIN FUNCTION ( µ PD78058FY SUBSERIES)
(1) Port pins (3/3)
Pin Name Input/Output Function After Reset Alternate Function
P120 to P127 Input/ Port 12. Input RTP0 to RTP7
output 8-bit input/output port.
Input/output mode can be specified bit-wise.
If used as an input port, an on-chip pull-up resistor can be used by software.
P130 to P131 Input/ Port 13. Input ANO0 to ANO1
output 2-bit input/output port.
Input/output mode can be specified bit-wise.
If used as an input port, an on-chip pull-up resistor can be used by software.
Cautions For pins which have alternate functions as port output, do not execute the following
operations during A/D conversion. If performed, then the general error standards cannot
be maintained during A/D conversion.
<1> If it is used as a port, rewriting the output latch of its output.
<2> Even if it is not used as a port, changing the output level of pins used as outputs.
