CHAPTER 6 TIMER ARRAY UNIT
Remark
pq: Unit number + Channel number (only for channels provided with timer I/O pins)
<1> 78K0R/LF3:
• p = 0, q = 0 to 4, 7 (q = 0, 2, 4 for master channel)
q < r ≤ 7 (where r is a consecutive integer greater than q)
<2> 78K0R/LG3:
• p = 0, q = 0 to 7 (q = 0, 2, 4, 6 for master channel)
q < r ≤ 7 (where r is a consecutive integer greater than q)
<3> 78K0R/LH3:
• p = 0, q = 0 to 7 (q = 0, 2, 4, 6 for master channel)
q < r ≤ 7 (where r is a consecutive integer greater than q)
• p = 1, q = 0 to 3 (q = 0, 2 for master channel)
q < r ≤ 3 (where r is a consecutive integer greater than q)
(13) Input switch control register (ISC)
ISC is used to implement LIN-bus communication operation with channel 7 of timer array unit 0 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.

Switching channel 7 input of timer array unit
Uses the input signal of the TI07 pin as a timer input (normal operation).
Input signal of RXD3 pin is used as timer input (wakeup signal detection).
Caution Be sure to clear bits 5 to 7 to “0”.
Remarks 1.
2.
When the LIN-bus communication function is used, select the input signal of the RxD3 pin by setting
ISC1 to 1.
Bits 0 and 2 to 4 of ISC are not used with TAU0.
