Section 22 I/O Ports
22.2.1
Table 22.3 lists the port B registers.
Table 22.3 Register Configuration
22.2.2
PBDRH and PBDRL are 16-bit readable/writable registers that store port B data. Bits PB31DR to
PB0DR correspond to pins PB31 to PB0, respectively.
If a pin is set to the general output function, the pin will output the value written to the
corresponding bit in PBDRH or PBDRL, and the register value is read from PBDRH or PBDRL
regardless of the state of the pin.
If a pin is set to the general input function, the pin state, not the register value, will be returned if
PBDRH or PBDRL is read. Also, if a value is written to PBDRH or PBDRL, although the value
will actually be written, it will have no influence on the state of the pin. Table 22.4 summarizes
the PBDRH and PBDRL read/write operations.
PBDRH and PBDRL are initialized to H'0000 by a power-on reset or in deep standby mode. These
registers are not initialized either by a manual reset or by switching to sleep mode or software
standby mode.
