5 0 Registers
5 33 CMT CONDITION REGISTER (CMTCR)
The CMT Condition Register maintains a history of all CMT events and actions performed The corresponding CMT Condition
Mask Register (CMTCMR) can be used to generate an interrupt When the bits in both the CMTCMR and CMTCR are set the
Receive Condition Register B’s Connection Service Event (RCRB CSE) bit will be set

SCRUB TIMER EXPIRED This bit is set to 1 when the Scrub Timer expires
Note When STE is set the Configuration Register (CR) is protected
TRIGGER CONDITION OCCURRED This bit is set to 1 when a trigger condition is met When a trigger occurs
the values in the Trigger Transmit Mode (TDR TTM2-0) are loaded into the Current Transmit Mode Register
(CTSR TM2-0)
Note When TCO is set the Current Transmit State Register (CTSR) is protected
