NOTE:
PTY — Parity Bit
Changing the PTY bit in the middle of a transmission or reception can
generate a parity error.

Control Bits
1 = Odd parity
0 = Even parity
Enables the following CPU interrupt requests:
– Enables the SCTE bit to generate transmitter CPU interrupt
– Enables the TC bit to generate transmitter CPU interrupt
– Enables the SCRF bit to generate receiver CPU interrupt
– Enables the IDLE bit to generate receiver CPU interrupt
