Bit 15 — Enable Timer: When this bit is set, the timer TCNTR is running. When this bit is 
cleared, TCNTR and CCR are cleared. 
Bit15: TTCR0 15 
Description 
Timer and CCR are cleared and disabled (initial value) 
Timer is running 
 
Bit 14 — TimeStamp value: Specifies if the Timestamp for transmission and reception in 
Mailboxes 15 to 0 must contain the Cycle Time (CYCTR) or the concatenation of CCR[5:0] + 
CYCTR[15:6]. This feature is very useful for time triggered transmission to monitor Rx_Trigger. 
This register does not affect the TimeStamp for Mailboxes 30 and 31. 
Bit14: TTCR0 14 
Description 
CYCTR[15:0] is used for the TimeStamp in Mailboxes 15 to 0 (initial value) 
CCR[5:0] + CYCTR[15:6] is used for the TimeStamp in Mailboxes 15 to 0 
 
Bit 13 — Cancellation by TCMR2: The messages in the transmission queue are cancelled by 
setting TXCR, when both this bit and bit12 are set and compare match occurs when this module is 
not in the Halt status, causing the setting of all TXCR bits with the corresponding TXPR bits set. 
Bit13: TTCR0 13 
Description 
0 Cancellation 
by TCMR2 compare match is disabled (initial value) 
1 Cancellation 
by TCMR2 compare match is enabled
