Section 17 I/O Ports (I/O)
17.9.2
The port H data register (PHDR) is a 16-bit read-only register that stores port H data. Bits
PH15DR to PH0DR correspond to pins PH15/AN15 to PH0/AN0.
Writes to these bits are ignored, and do not affect the pin states. When these bits are read, the pin
state, not the register value, is returned directly. However, 1 will be returned while A/D converter
analog input is being sampled. Table 17.16 summarizes port H data register read/write operations.
PHDR is not initialized by a power-on reset, or in hardware standby mode, software standby
mode, or sleep mode. (The bits always reflect the pin states.)

17.10
The output port drive buffers for the address bus pins (A20 to A0) and data bus pins (D15 to D0)
can be controlled by the POD (port output disable) pin input level. However, this function is
enabled only when the address bus pins (A20 to A0) and data bus pins (D15 to D0) are designated
as general output ports.
Output buffer control by means of POD is performed asynchronously from bus cycles.
