Serial Control Module: UART
Serial Channel B/A/C/D Control Register A

Address: 9020 0000 / 0040

9030 0000 / 0040

There are two Serial Channel B/A/C/D Control Registers A within each two-channel

serial controller module.
Register bit assignment
Bits Access Mnemonic Reset Description
D31 R/W CE 0 Channel enable
0 Resets the port and the data FIFOs (disables the
channel)
1 Enables a serial channel operation
The CE field must not be set until all control bits in Serial
Channel Control Register A, Control Register B, and Bit-
rate register have been defined.
D30 R/W BRK 0 Send break
Forces a break condition in UART mode. While BRK is
set to 1, the UART transmitter outputs a logic 0 or a space
condition on the TXD output signal.
D29 R/W STICKP 0 Stick parity
Can be used to force the UART parity field to a certain
state as defined by the EPS field (see D28), instead of a
parity bit calculated against the data word. STICKP
applies only when the PE field (see D27) is also set to 1.
Set STICKP to 1 to force transmission of the static parity
value.
