Receive Character-Based Flow Control register
Address: 9001_1028 / 9001_9028 / 9002_1028 / 9002_9028
The Receive Character-Based Flow Control register lets you define the UART
module’s receive character-based flow control operation. Use this register in
conjunction with the Receive Character Match Control registers to define the flow
control characters. If enabled, this function’s output is wired to the UART module
instead of the CTS signal.

Bits Access Mnemonic Reset Description
D31 R/W ENABLE 0 Enable character match
Write a 1 to enable the receive character match control
logic.
D30:24 R Not used 0x0 Write this field to 0.
D23:16 R/W MASK 0x0 Mask
Allows you to not include specific bits in the receive
character match operation. Writing 1 masks off the bit in
the specified position.
Bit positions that are not used should always be masked.
For example, bit positions 9 through 12 should always be
masked for 8-bit characters.
D15:08 R Not used 0x0 Write this field to 0.
D07:00 R/W DATA 0x0 Data
Allows you to specify the receive characters to match
against.
