Hitachi SH7032 - Port B Control Registers (PBCR1 and PBCR2)

434
15.3.4 Port B Control Registers (PBCR1 and PBCR2)
PBCR1 and PBCR2 are 16-bit read/write registers that select the functions of the sixteen
multiplexed pins of port B. PBCR1 selects the function of the upper eight bits of port B; PBCR2
selects the function of the lower eight bits of port B. PBCR1 and PBCR2 are initialized to H'0000
by a power-on reset, but are not initialized by a manual reset, or in standby mode or sleep mode.
