17.2.1 LIN Registers for Master Mode
(1) Input Switch Control Register (ISC)
The ISC2 and ISC3 bits in the ISC register are used in the LIN/UART module (RLIN3).
Setting bit 2 or bit 3 to 1 selects the input signal of the serial data input pin for the LIN/UART module as the external interrupt
input.
This register can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation sets this register to 00H.
ddress: F0073H After reset: 00H R/W
Symbol 7 6 5 4 3 2 1 0
ISC 0 0 0 0 ISC3 ISC2 0 ISC0
ISC3 Switching inputs for external interrupt INTP12
0 INTP12 pin input signal is set as external interrupt input.
1 LRXD1 pin input signal is set as external interrupt input.
ISC2 Switching inputs for external interrupt INTP11
0 INTP11 pin input signal is set as external interrupt input.
1 LRXD0 pin input signal is set as external interrupt input.
ISC0 Switching inputs for external interrupt INTP0
0 INTP0 pin input signal is set as external interrupt input. (normal operation)
1 RXD0 pin input signal is set as external interrupt input. (wake-up signal detection)
Caution Bits 7 to 4 and 1 should always be set to 0.
