HIGH. The infrared pulse can be inverted internally prior to decoding by setting
FCTR bit-4.
O ^{UART channel 4 Request to Send or general purpose output (active LOW). See}
description of RTS0# pin.
I ^{UART channel 4 Clear to Send or general purpose input (active LOW). See descrip-}
tion of CTS0# pin.
O ^{UART channel 4 Data Terminal Ready or general purpose output (active LOW). See}
description of DTR0# pin.
I ^{UART channel 4 Data Set Ready or general purpose input (active LOW). See}
description of DSR0# pin.
I ^{UART channel 4 Carrier Detect or general purpose input (active LOW).}
I ^{UART channel 4 Ring Indicator or general purpose input (active LOW).}
