ISC
(7)
Input switch control register (ISC)
The segment output pins to be used alternatively with the TI04, TI02, and RxD3 pins are internally connected with
a Schmitt trigger buffer. To use these pins as segment outputs, input to the Schmitt trigger buffer must be
disabled, in order to prevent through-currents from entering.
ISC is set using a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation sets ISC to 00H.
Remark
Remark
To use the TI04/SEGxx/P53, TI02/SEGxx/P52, and RxD3/SEGxx/P50 pins, set the PF5L and ISCn (n = 2 to 4)
bits as follows, according to the function to be used.
Caution Be sure to clear bits 5 to 7 to “0”.
