IRDAM0
0 UART (transmit/receive) mode
1 Infrared data transfer (transmit/receive) mode
Notes 1. The UART/infrared data transfer mode specification is controlled by TXE0 and RXE0.
2. When using infrared data transfer mode, be sure to set the baud rate generator control register
(BRGC0) to 10H.
Caution Do not switch the operation mode until the current serial transmit/receive operation has
stopped.
