Description
Clock Select 0 and 1
These bits select the clock source for the baud rate
generator.
00:
01: /4 clock (n = 1)
10: /16 clock (n = 2)
11: /64 clock (n = 3)
For the relationship between the bit rate register setting
and the baud rate, see section 16.3.8, Bit Rate Register
(BRR). n is the decimal representation of the value of n in
BRR (see section 16.3.8, Bit Rate Register (BRR)).
Description
Transmit Interrupt Enable
When this bit is set to 1, the 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 s set to 1, transmission is enabled.
Receive Enable
When this bit is set to 1, reception is enabled.
