20.2.1
Table 20.3 lists the port B registers.
Table 20.3 Register Configuration
20.2.2
PBDRH and PBDRL are 16-bit readable/writable registers that store port B data. Bits PB30DR
and PB0DR correspond to pins PB30 to PB0, respectively.
When a pin function is general output, if a value is written to PBDRH or PBDRL, the value is
output directly from the pin, and if PBDRH or PBDRL is read, the register value is returned
directly regardless of the pin state.
When a pin function is general input, if PBDRH or PBDRL is read, the pin state, not the register
value, is returned directly. If a value is written to PBDRH or PBDRL, although that value is
written into PBDRH or PBDRL, it does not affect the pin state. Table 20.4 summarizes PBDRH
and PBDRL read/write operations.
PBDRH and PBDRL are initialized to the value shown in table 20.3 by a power-on reset, but are
not initialized by a manual reset or in sleep mode or software standby mode.
