• Manufacturer Part Number: HD6412350
• Description: (HD6412350 / HD6432351) 16-BIT MICROCONTROLLER
• Manufacturer: Hitachi

Bits 7 to 4 are reserved; they return an undetermined value if read, and cannot be modified.
If a port 5 read is performed while P5DDR bits are set to 1, the P5DR values are read. If a port 5
read is performed while P5DDR bits are cleared to 0, the pin states are read.
After a power-on reset and in hardware standby mode, PORT5 contents are determined by the pin
states, as P5DDR and P5DR are initialized. PORT5 retains its prior state after a manual reset, and
in software standby mode.

Port 5 pins also function as the A/D converter input pin (ADTRG). Port 5 pin functions are shown
in table 9-10.

Selection Method and Pin Functions
The pin function is switched as shown below according to the combination of
bits TRGS1 and TRGS0 in the A/D converter ADCR, and bit P53DDR.
Note: * ADTRG input when TRGS0 = TRGS1 = 1.
The pin function is switched as shown below according to bit P52DDR.
The pin function is switched as shown below according to bit P51DDR.
The pin function is switched as shown below according to bit P50DDR.
