(14) Input switch control register (ISC)
Symbol
ISC
Caution Be sure to clear bits 7 to 5 to “0”.
Remark Bits 2 to 4 of ISC are not used with SAU1.
ISC is used to realize a LIN-bus communication operation by UART3 in coordination with an external interrupt and
the timer array unit.
When bit 0 is set to 1, the input signal of the serial data input (R
(INTP0) that can be used to detect a wakeup signal.
When bit 1 is set to 1, the input signal of the serial data input (R
pulse widths of a sync break field and a sync field can be measured by the timer.
ISC can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation clears this register to 00H.

Uses the input signal of the TI07 pin as a timer input (normal operation).
Input signal of R
Uses the input signal of the INTP0 pin as an external interrupt (normal operation).
Uses the input signal of the R
(to measure the pulse widths of the sync break field and sync field).
