Description
Clock Select 1 and 0
These bits select the clock source for the baud rate
generator.
00: Pφ clock (n = 0)
01: Pφ/8 clock (n = 1)
10:Pφ/32 clock (n = 2)
11:Pφ/128 clock (n = 3)
For the relation between the bit rate register setting
and the baud rate, see section 12.3.9, Bit Rate
Register (BRR). n is the decimal display of the value
of n in BRR (see section 12.3.9, Bit Rate Register
(BRR)).
Description
Transmit Interrupt Enable
When this bit is set to 1, 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.
