Bit 7: BDLAB. When this bit is set to a logical 1, designers can access the divisor (in 16-bit binary
Bit 6: SSE. A logical 1 forces the Serial Output (SOUT) to a silent state (a logical 0). Only IRTX is
Bit 5: PBFE. When PBE and PBFE of UCR are both set to a logical 1,
(1) if EPE is logical 1, the parity bit is fixed as logical 0 to transmit and check.
(2) if EPE is logical 0, the parity bit is fixed as logical 1 to transmit and check.

When this bit is reset, the Receiver Buffer Register, the Transmitter Buffer Register, or the
Interrupt Control Register can be accessed.
