Function

General-purpose I/O port: Valid when the data output specification is

prohibited on LIN-UART2.

LIN-UART2 data output: Valid when the data output specification is

permitted on LIN-UART2.

Chip select 1 output: Valid when the output specification is permitted on

chip select 1.

General-purpose I/O port: Valid when clock output is prohibited on

LIN-UART2.

LIN-UART2 clock input/output: Valid when the clock output specification is

permitted on LIN-UART2.

Chip select 2 output: Valid when the output specification is permitted on

chip select 2.

General-purpose I/O port: Valid when the data input specification is

prohibited on LIN-UART3.

LIN-UART3 data input. Because this input is used as necessary while LIN-

UART3 is used for input operation, the port output needs to be disabled

except when it is used intentionally.

External clock input for free-run timer 1

Chip select 3 output: Valid when the output specification is permitted on

chip select 3.

General-purpose I/O port: Valid when data output specification is

prohibited on LIN-UART3.

LIN-UART3 data output: Valid when the data output specification is

permitted on LIN-UART3.

External bus read strobe output: Valid at the external bus mode.

General-purpose I/O port: Valid when clock output is prohibited on

LIN-UART3.

LIN-UART3 clock input/output: Valid when the clock output specification is

permitted on LIN-UART3.

External bus write strobe output: Valid when the WR0X output is permitted

at the external bus mode.

General-purpose I/O port

Output compare output

External bus write strobe output: Valid when the WR1X output is permitted

at the external bus mode.

General-purpose I/O port

Output compare output

External ready input: Valid when the external ready input specification is

permitted.
