(18) Port mode registers 1, 3, 7 (PM1, PM3, PM7)
Note The PM1 and P1 registers are only provided in the 78K0R/IB3. The PM7 and P7 registers are not
These registers set input/output of ports 1
When using the ports (such as P30/SO10/TxD1/TO11, P32/SCK10/SCL10/INTP2) to be shared with the serial
data output or serial clock output pin for serial data output or serial clock output , set bit of the port mode
register (PMxx) to 0 and bit of port register (Pxx) to 1.
Example: When using P30/SO10/TxD1/TO11 for serial data output
When using the ports (such as P71/SI01/INTP5, P72/SCK01/INTP6) to be shared with the serial data input or
serial clock input pin for serial data input or serial clock input , set bit of the port mode register (PMxx) to 1.
The bit of the port register (Pxx) at this time may be 0 or 1.
Example: When using P71/SI01/INTP5 for serial data input
PM1, PM3, and PM7
Reset signal generation sets these registers to FFH.
provided in the 78K0R/IB3.
Set the PM30 bit of port mode register 3 to 0.
Set the P30 bit of port register 3 to 0.
Set the PM71 bit of port mode register 7 to 1.
Set the P71 bit of port register 7 to 0 or 1.
Note
can be set by a 1-bit or 8-bit memory manipulation instruction.
