26.3.1.20 Trigger Transfer to Communication Controller Set/Reset (TTCCS[1-4]/TTCCR[1-4])
The Trigger Transfer to Communication Controller registers select the current message buffer for a
Transfer Unit State Machine transfer transaction from system memory. Four 32-bit registers reflect all
possible 128 message buffers.
The bits are set by writing 1 to TTCCSx and reset by writing 1 to TTCCRx or after the transfer occurred.
Writing a 0 has no effect. Reading from both addresses will result in the same value.

Bit Field Value Description
31-0 TTCCS1(31-0) Trigger Transfer to Communication Controller Set 1.
The register bits 0 to 31 correspond to message buffers 0 to 31. Each bit of the register controls the
message buffer transfer to the communication controller in the following manner:
0 No transfer request.
1 Transfer based on address defined in TBA.
