TMRCK
A10
I
16-bit timer/counter external clock input.
EN485#
C10
I
Auto RS-485 mode enable (active low). This pin is sampled during power up,
following a hardware reset (RST#) or soft reset (register RESET). It can be
used to start up all 4 UARTs in the Auto RS-485 Half-Duplex Direction control
mode. The sampled logic state is transferred to FCTR bit-5 in the UART
channel.
ENIR#
B10
I
Infrared mode enable (active low). This pin is sampled during power up, fol-
lowing a hardware reset (RST#) or soft-reset (register RESET). It can be
used to start up all 4 UARTs in the infrared mode. The sampled logic state is
transferred to MCR bit-6 in the UART.
