(7) Input switch control register (ISC)
350
By setting ISC5 to 1, the UART6 I/O pins are switched from P113/SEG7/RxD6 and P112/SEG6/TxD6 to
P12/RxD0/KR3/RxD6 and P13/TxD0/KR4/TxD6.
By setting ISC3 to 1, the P113/SEG7/RxD6 pin is enabled for input. When ISC3 is cleared to 0, external input is
not acknowledged. Thus, after release of reset, a generation of a through current due to an undetermined input
state until an output setting is performed is prevented.
The input switch control register (ISC) is used to receive a status signal transmitted from the master during LIN
(Local Interconnect Network) reception.
By setting ISC0 and ISC1 to 1, the input sources of INTP0 and TI000 are switched to input signals from the
P12/RxD0/KR3/RxD6 or P113/SEG7/RxD6 pin.
This register can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation sets this register to 00H.
Notes 1. TI52 input is controlled by TOH2 output signal.
