78K0R/Lx3
CHAPTER 14 SERIAL ARRAY UNIT
(18) Port mode registers 1, 5, 7, 8 (PM1, PM5, PM7, PM8)
These registers set input/output of ports 1, 5, 7 and 8 in 1-bit units.
When using the P10/SCK20/SCL20, P11/SI20/SDA20/RxD2/INTP6, P12/SO20/TxD2/TO02, P13/SO10/TxD1/TO04,
P14/SI10/SDA10/RxD1/INTP4, P15/SCK10/SCL10/INTP7, P51/TxD3/SEGx (78K0R/LF3: x = 29, 78K0R/LG3: x = 38,
78K0R/LH3: x = 52), P75/SCK01/KR5, P77/SO01/KR7, P80/SCK00/INTP11, and P82/SO00/TxD0 pins for serial data
output or serial clock output, clear the PM10, PM11, PM12, PM13, PM14, PM15, PM51, PM75, PM77, PM80, and
PM82 bits to 0, and set the output latches of P10, P11, P12, P13, P14, P15, P51, P75, P77, P80, and P82 to 1.
When using the P10/SCK20/SCL20, P11/SI20/SDA20/RxD2/INTP6, P14/SI10/SDA10/RxD1/INTP4,
P15/SCK10/SCL10/INTP7, P50/RxD3/SEGx (78K0R/LF3: x = 30, 78K0R/LG3: x = 39, 78K0R/LH3: x = 53),
P75/SCK01/KR5, P76/SI01/KR6, P80/SCK00/INTP11, and P81/SI00/RxD0/INTP9 pins for serial data input or serial
clock input, set the PM10, PM11, PM14, PM15, PM50, PM75, PM76, PM80, and PM81 bits to 1. At this time, the
output latches of P10, P11, P14, P15, P50, P75, P76, P80, and P81 may be 0 or 1.
PM1, PM5, PM7, and PM8 can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation sets these registers to FFH.
