Section 26 I/O Ports
26.2
Port A is an input/output port with eight pins as shown in figure 26.1.
26.2.1
Table 26.1 lists the port A registers.
Table 26.1 Register Configuration
26.2.2
PADRL is a 16-bit read-only register that stores port A data. The PA7DR to PA0DR bits
correspond to the PA7/AN7/DA1 to PA0/AN0 pins, respectively. The general input function of
the PA7 to PA0 pins is enabled only when the A/D and D/A converters are halted.
Writing to these bits is ignored, and therefore does not affect the pin state. If these bits are read,
the pin state, not the bit value, is directly returned. Note that, however, this register should not be
read during operation of the A/D or D/A converter. Table 26.2 summarizes PADRL read/write
operation.
