The port J control register (PJCR) is a 16-bit readable/writable register that selects the pin
functions. PJCR 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—PJ7 Mode 1 and 0 (PJ7MD1, PJ7MD0)
Bits 13 and 12—PJ6 Mode 1 and 0 (PJ6MD1, PJ6MD0)
Bits 11 and 10—PJ5 Mode 1 and 0 (PJ5MD1, PJ5MD0)
Bits 9 and 8—PJ4 Mode 1 and 0 (PJ4MD1, PJ4MD0)
Bits 7 and 6—PJ3 Mode 1 and 0 (PJ3MD1, PJ3MD0)
Bits 5 and 4—PJ2 Mode 1 and 0 (PJ2MD1, PJ2MD0)
Bits 3 and 2—PJ1 Mode 1 and 0 (PJ1MD1, PJ1MD0)
Bits 1 and 0—PJ0 Mode 1 and 0 (PJ0MD1, PJ0MD0)
These bits select the pin functions and perform input pull-up MOS control.
