There are two programmable communication timeout thresholds that monitor the absence of a valid frame from either UART or daisy chain communications. A valid frame is defined as any frame (response or command) that does NOT contain any errors that prevent the frame from being processed. These errors include: CRC errors, byte errors (COMM_*_FAULT[BERR] = 1), start of frame errors (COMM_*_FAULT[SOF] = 1), or frame initialization errors(COMM_*_FAULT[IERR] = 1). The communication timeouts are only actively counting while in ACTIVE mode. The counters are disabled and reset during SHUTDOWN mode. In Sleep mode, the last counter values are held frozen.
