CHAPTER 4 PORT FUNCTIONS
Table 4-1. Port Functions
I/O port. Input/output mode can be specified in 1-bit units.
An on-chip pull-up resistor can be used in 1-bit units by setting pull-up resistor option
register 0 (PU0).
Input-only port
I/O port. Input/output mode can be specified in 1-bit units.
An on-chip pull-up resistor can be used in 1-bit units by setting pull-up resistor option
register 2 (PU2).
I/O port. Input/output mode can be specified in 1-bit units.
P30 and P31 are 5 V N-ch open-drain I/O port. Mask ROM version of the µ PD780344,
780354 Subseries can specify an on-chip pull-up resistor in 1-bit units by mask option.
P32 to P35 can use an on-chip pull-up resistor in 1-bit units by setting pull-up resistor
option register 3 (PU3).
I/O port. Input/output mode can be specified in 1-bit units.
An on-chip pull-up resistor can be used in 1-bit units by setting pull-up resistor option
register 4 (PU4).
Sets the interrupt request flag (KRIF) to 1 by detecting a rising edge.
Middle-voltage N-ch open-drain I/O port. Input/output mode can be specified in 1-bit units.
Mask ROM version can specify an on-chip pull-up resistor in 1-bit units by mask option.
