32.2.31 Port J I/O register 0 (PJIOR0)
PJIOR0 is a 16-bit readable/writable register that is used to set the pins on port J as inputs or
outputs. The PJ11IIOR to PJ0IOR bits correspond to the PJ11 to PJ0 pins respectively. The setting
of PJIOR0 is valid for the pins for which general I/O (PJ11 to PJ0) function or TIOC I/O function
of multi-function timer pulse unit 2 is selected and has no effect on the pins for which other
function is selected. If a bit in PJIOR0 is set to 1, the corresponding pin on port J functions as an
output pin. If it is cleared to 0, the corresponding pin functions as an input pin.
Bits 15 to 12 in PJIOR0, and bits 11 to 4 in PJIOR0 in the SH7262 Group are reserved. These bits
are always read as 0. The write value should always be 0.
