Description
Clock select.
IR enable.
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
rate
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.
