Function

General-purpose I/O port pin : Valid when clock output of

LIN-UART0 is prohibited

I

LIN-UART0 clock input and output pin for serial communication :

Valid when clock output of LIN-UART0 is permitted

Output pin of chip select 0 : Valid when external bus mode is

selected

General-purpose I/O port pin

LIN-UART1 serial data output pin : Valid when data output of

I

LIN-UART1 is permitted

Output pin of chip select 1 : Valid when output of chip select 1 is

permitted

General-purpose I/O port pin

LIN-UART1 clock input and output pin for serial communication :

I

Valid when clock output of LIN-UART1 is permitted

Output pin of chip select 2 : Valid when output of chip select 2 is

permitted

General-purpose I/O port pin

Serial data input pin of LIN-UART2 : LIN-UART2, requiring output

by ports to be stopped while LIN-UART2 is performing input

operation, except when executed intentionally, as this input is

I

always in use

External clock input pin of free-run timer 1

Output pin of chip select 3 : Valid when output of chip select 3 is

permitted

General-purpose I/O port pin

Serial data output pin of LIN-UART2 : Valid when data output of

I

LIN-UART2 is permitted

Read strobe output pin of external bus : Valid when external bus

mode is selected
