The port K control register (PKCR) is a 16-bit readable/writable register that selects the pin
functions. PKCR is initialized to H'0000 by a power-on reset, but is not initialized by a manual
reset, in standby mode, or in sleep mode.
Bits 15 and 14—PK7 Mode 1 and 0 (PK7MD1, PK7MD0)
Bits 13 and 12—PK6 Mode 1 and 0 (PK6MD1, PK6MD0)
Bits 11 and 10—PK5 Mode 1 and 0 (PK5MD1, PK5MD0)
Bits 9 and 8—PK4 Mode 1 and 0 (PK4MD1, PK4MD0)
Bits 7 and 6—PK3 Mode 1 and 0 (PK3MD1, PK3MD0)
Bits 5 and 4—PK2 Mode 1 and 0 (PK2MD1, PK2MD0)
Bits 3 and 2—PK1 Mode 1 and 0 (PK1MD1, PK1MD0)
Bits 1 and 0—PK0 Mode 1 and 0 (PK0MD1, PK0MD0)
These bits select the pin functions and perform input pull-up MOS control.
