(14) Input switch control register (ISC)
Symbol
ISC
Caution Be sure to clear bits 7 to 2 to “0”.
Remark
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
the 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.
ISC1
ISC0
Since the 78K0R/KE3 does not have the timer input pin on channel 7, normally the timer input on
channel 7 cannot be used. When the LIN-bus communication function is used, select the input
signal of the RxD3 pin by setting ISC1 to 1.
