Description
Transmit Interrupt Enable
When this bit is set to 1,a TXI interrupt request is
enabled.
Receive Interrupt Enable
When this bit is set to 1, RXI and ERI interrupt
requests are enabled.
Transmit Enable
When this bit is set to 1, transmission is enabled.
Receive Enable
When this bit is set to 1, reception is enabled.
Multiprocessor Interrupt Enable (enabled only
when the MP bit in SMR is 1 in asynchronous
mode)
Write 0 to this bit in smart card interface mode.
Transmit End Interrupt Enable
Write 0 to this bit in smart card interface mode.
Clock Enable 1 and 0
Controls the clock output from the SCK pin. In
GSM mode, clock output can be dynamically
switched. For details, see section 14.7.8, Clock
Output Control.
