s PERIPHERAL FUNCTIONS
1. I/O Ports
The I/O ports function is to send data from the CPU to be output from I/O pins and load input signals at the I/O
pins into the CPU, according to the port data register (PDR) . Port input/output at I/O pins can be controlled in
bit units by the port direction register (DDR) as required. The following list shows each of the functions as well
as the shared peripheral function for each port.
• Port 0 : General purpose I/O port, shared with peripheral functions (external interrupt/UART/PPG)
• Port 1 : General purpose I/O port, shared with peripheral functions (PPG/reload timer/clock timer/ICU)
• Port 3 : General purpose I/O port, shared with peripheral functions (LCD)
• Port 4 : General purpose I/O port, shared with peripheral functions (LCD)
• Port 5 : General purpose I/O port, shared with peripheral functions (External interrupt/CAN/SG)
• Port 6 : General purpose I/O port, shared with peripheral functions (A/D converter)
• Port 7 : General purpose I/O port, shared with peripheral functions (Stepping motor controller)
• Port 8 : General purpose I/O port, shared with peripheral functions (Stepping motor controller)
• Port 9 : General purpose I/O port, shared with peripheral functions (LCD)
