Section 20 I/O Ports
20.4.2
PCDRL is a 16-bit readable/writable register that stores port C data. Bits PC1DR and PC0DR
correspond to pins PC1/A1 and PC0/A0, respectively.
When a pin function is general output, if a value is written to PCDRL, that value is output directly
from the pin, and if PCDRL is read, the register value is returned directly regardless of the pin
state.
When a pin function is general input, if PCDRL is read, the pin state, not the register value, is
returned directly. If a value is written to PCDRL, although that value is written into PCDRL, it
does not affect the pin state. Table 20.6 summarizes PCDRL read/write operations.
PCDRL is initialized to the value shown in table 20.5 by a power-on reset. PCDRL is not
initialized by a manual reset or in sleep mode or software standby mode.
