PMR1 is an 8-bit read/write register, controlling the selection of pin functions for port 1 pins.
Upon reset, PMR1 is initialized to H'00.
Bit 7—P1₇/IRQ₃/TMIF Pin Function Switch (IRQ3): This bit selects whether pin
P1₇/IRQ₃/TMIF is used as P1₇ or as IRQ₃/TMIF.
Bit 7: IRQ3
Description
0
1
Note:
Functions as P1₇ I/O pin
(initial value)
Functions as IRQ₃/TMIF input pin
Rising or falling edge sensing can be designated for IRQ₃/TMIF.
For details on TMIF pin settings, see 9.5.2 (3), timer control register F (TCRF).
Bit 6—P1₆/IRQ₂/TMIC Pin Function Switch (IRQ2): This bit selects whether pin
P1₆/IRQ₂/TMIC is used as P1₆ or as IRQ₂/TMIC.
Bit 6: IRQ2
Description
0
1
Note:
Functions as P1₆ I/O pin
Functions as IRQ₂/TMIC input pin
Rising or falling edge sensing can be designated for IRQ₂/TMIC.
For details on TMIC pin settings, see 9.4.2 (1), timer mode register C (TMC).
(initial value)
Bit 5—P1₅/IRQ₁/TMIB Pin Function Switch (IRQ1): This bit selects whether pin
P1₅/IRQ₁/TMIB is used as P1₅ or as IRQ₁/TMIB.
Bit 5: IRQ1
Description
0
1
Note:
Functions as P1₅ I/O pin
Functions as IRQ₁/TMIB input pin
Rising or falling edge sensing can be designated for IRQ₁/TMIB.
For details on TMIB pin settings, see 9.3.2 (1), timer mode register B (TMB).
