Description
MCR[7]
Clock select.
Logic 0 = Divide-by-1. The input clock (crystal or external) is
divided by 16 and then presented to the Programmable Baud Rate
Generator (BGR) without further modification, i.e., divide-by-1
(normal default condition).
Logic 1 = Divide-by-4. The divide-by-1 clock described in MCR[7]
equals a logic 0, is further divided by four (see also
Section 6.7
“Programmable baud rate generator”
).
MCR[6]
IR enable.
Logic 0 = Enable the standard modem receive and transmit
input/output interface (normal default condition).
Logic 1 = Enable infrared IrDA receive and transmit inputs/outputs.
While in this mode, the TX/RX output/inputs are routed to the
infrared encoder/decoder. The data input and output levels will
conform to the IrDA infrared interface requirement. As such, while
in this mode, the infrared TX output will be a logic 0 during idle data
conditions.
