Address: FFD0 001C / 5C
When the serial channel is configured for UART mode, the Receive Match register
provides the data bytes that the receiver uses to compare against the incoming
receive data stream. If a match is found and the appropriate match enable bit is set
in Serial Channel Control Register B, the current receive data buffer is closed by the
serial channel and a new buffer is started.
In UART configurations, individual bits within the match register bytes can be masked
using the Receive Match MASK register (see "Serial Channel 1, 2 Receive Match MASK
register" on page 254).
Register bit assignment
Table 94: Serial Channel Receive Match register bit definition
Address: FFD0 0020 / 60
The Receive Match MASK register masks those bits in the Receive Match Data register
that should not be included in the match comparison. To mask a bit in the match
comparison function, place a 1 in the same bit position in this register.
