Jul 15, 2010
The input switch control register (ISC) is used to receive a status signal transmitted from the master during LIN (Local
Interconnect Network) reception.
The signal input from the P14/R
set to 1.
This register can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation sets this register to 00H.
This register sets port 1 input/output in 1-bit units.
When using the P13/T
When using the P14/R
be 0 or 1.
PM1 can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation sets this register to FFH.
