38.7.11 Timeout Counter Value

Note: A write access to TOCV reloads the Timeout Counter with the value of bit TOCC.TOP (TOCC<31:16>).

Bits 15:0 – TOC[15:0] Timeout Counter

The Timeout Counter is decremented in multiples of CAN bit times [1...16] depending on the configuration of the TSCC.TCP bit (TSCC<19:16>). When decremented to zero, interrupt flag (IR.TOO bit (IR<18>)) is set and the Timeout Counter is stopped. Start and reset/restart conditions are configured via TOCC.TOS bit (TOCC<2:1>).
