26.3.2
PBDRL is a 16-bit readable/writable register that stores port B data. The PB12DR to PB0DR bits
correspond to the PB12/WDTOVF/IRQOUT/REFOUT/UBCTRG to PB0/SCL0/PINT0/IRQ0
pins, respectively.
When a pin function is general output, if a value is written to PBDRL, that value is output directly
from the pin, and if PBDRL is read, the register value is returned directly regardless of the pin
state.
When a pin function is general input, if PBDRL is read, the pin state, not the register value, is
returned directly. If a value is written to PBDRL, although that value is written into PBDRL, it
does not affect the pin state. Table 26.4 summarizes PBDRL read/write operations.
