ISC
Remark Since the 78K0R/KE3 does not have the timer input pin on channel 7, normally the timer input on
ISC is used to implement LIN-bus communication operation with channel 7 in association with serial array unit
1.
When bit 1 of this register is set to 1, the input signal of the serial data input pin (RxD3) is selected as a timer
input signal.
ISC can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation clears this register to 00H.
Caution Be sure to clear bits 7 to 2 to “0”.
NFEN1 is used to set whether the noise filter can be used for the timer input signal to each channel.
Enable the noise filter by setting the corresponding bits to 1 on the pins in need of noise removal.
When the noise filter is ON, match detection and synchronization of the 2 clocks is performed with the
CPU/peripheral hardware clock (f

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 and setting TIS07 (bit 7 of the timer input select register
