CHARACTER1-8—Control Character Values
E—End of Table
R—Reject character
RCCM—Received Control Character Mask
MOTOROLA
These fields define control characters that should be compared to the incoming character.
For less than 8 bits characters, the msb bits should be zero.
The value in this register is used to mask the comparison of CHARACTER1 through
CHARACTER8. The lower eight bits of RCCM correspond to the lower eight bits of
CHARACTER1-8, and are decoded as follows.
OFFSET + 10
OFFSET +1 2
OFFSET + E
OFFSET + 0
OFFSET + 2
OFFSET + 4
OFFSET + 6
0 = This entry is valid. The lower 8 bits will be checked against the incoming character.
1 = The entry is not valid. This must be the last entry in the Control Characters Table.
0 = The character is not rejected but written into the receive buffer. The buffer is then
1 = If this character is recognized it will not be written to the receive buffer. Instead, it
0 = Mask this bit in the comparison of the incoming character, and CHARACTER1
1 = The address comparison on this bit proceeds normally. No masking takes place.
closed and a new receive buffer is used if there is more data in the message. A
maskable (I Bit in the Receive BD) interrupt is generated.
is written to the Received Control Characters Register (RCCR) and a maskable in-
terrupt is generated. The current buffer is not closed when a control character is
received with R set.

In tables with 8 control characters this bit is always 0.
The two most significant bits (bit 15 and bit 14) of RCCM must
be set, or erratic operation may occur during the control charac-
ter recognition process.
