(2) Pull-up resistor option registers (PU0, PU2 to PU7)
Cautions 1. The P10 to P17 pins do not incorporate a pull-up resistor.
These registers are used to set whether to use an on-chip pull-up resistor at each port or not. By setting PU0
and PU2 to PU7, the on-chip pull-up resistors of the port pins corresponding to the bits in PU0 and PU2 to PU7
can be used.
PU0 and PU2 to PU7 are independently set by a 1-bit or 8-bit memory manipulation instruction.
RESET input clears registers to 00H.
2. Pins P30 to P33 (in PD780024AY and 780034AY Subseries, P30 and P31 pins) can be used
3. When PUm is set to 1, the on-chip pull-up resistor is connected irrespective of the input/
with pull-up resistor by mask option only for mask ROM version.
output mode. When using in output mode, clear the bit of PUm to 0 (m = 0, 2 to 7).
