22.2.3 Port B Port Register L (PBPRL)
The port B port register L (PBPRL) is a 16-bit read-only register that always returns the states of
the pins regardless of the PFC setting. Bits PB9PR to PB4PR and PB2PR to PB0PR correspond to
pins PB9 to PB4 and PB2 to PB0, respectively (multiplexed functions omitted here) in the
SH7083. Bits PB9PR to PB0PR correspond to pins PB9 to PB0 (multiplexed functions omitted
here) in the SH7084, SH7085, and SH7086
