• Manufacturer Part Number: upd78f0148m1gka1-9eu
• Description: 8-bit Single-chip Microcontrollers
• Manufacturer: Renesas Electronics Corporation.

(3) Port mode registers 0 and 1 (PM0, PM1)
These registers set port 0 and 1 input/output in 1-bit units.
When using P10/SCK10 and P04/SCK11
to 0 and set the output latches of P10 and P04 to 1. When using P12/SO10 and P02/SO11
pins of the serial interface, clear PM12 and PM02, and the output latches of P12 and P02 to 0.
When using P10/SCK10 and P04/SCK11
P03/SI11
PM03, and PM05 to 1. At this time, the output latches of P10, P04, P11, P03, and P05 may be 0 or 1.
PM0 and PM1 can be set by a 1-bit or 8-bit memory manipulation instruction.
RESET input sets these registers to FFH.
