Section 24 I/O Ports
24.2.3 Port B Port Registers H and L (PBPRH and PBPRL)
PBPRH and PBPRL are 16-bit read-only registers, which always return the states of the pins
regardless of the PFC setting. In SH7243, Bits PB12PR to PB11PR, PB8PR to PB6PR, PB1PR
and PB0PR correspond to pins PB12 to PB11, PB8 to PB6, PB1PR and PB0PR respectively
(description of multiplexed functions are abbreviated here). In SH7285, Bits PB12PR to PB6PR,
PB3PR to PB0PR correspond to pins PB12 to PB6, PB3 to PB0 respectively (description of
multiplexed functions are abbreviated here). In SH7286, Bits PB19PR to PB6PR and PB3PR to
PB0PR correspond to pins PB19 to PB6 and PB3 to PB0 respectively (description of multiplexed
functions are abbreviated here).
