Pin Functions
(a)
Normal Extended Mode and Address-Data Multiplex Extended Mode
Port C pins can also function as the bus control output and IIC_2, IIC_3, and IIC_4 input/output
pins. The relationship between register setting values and pin functions are as follows.
•
PC7
The PC7 pin functions as a bus control output pin.
•
PC6
When set for 16-bit bus width, the PC7 pin functions as a bus control output pin. When 8-bit
bus width, the pin function is the same as that in single-chip mode.
•
PC5 to PC0
The pin functions are the same as those in single-chip mode.
(b)
Single-Chip Mode
•
PC7, PC6
The pin function is switched as shown below according to the PCnDDR bit.
