Problems placing TJA1145 CAN Transceiver into sleep mode

I have seemingly tried everything to get the TJA1145 into sleep mode. According to the data sheet the TJA1145 will enter sleep mode if "there are no pending wake-up events and at least one regular wake-up source" I have tried using both the WAKE pin and the partial networking features with no luck. CWE is enabled, CW is cleared, WPRE and WPFE are enabled, PNCOK is configured correctly, CPNC is enabled. Still when the TJA1145 is set to sleep mode (MC = 001) it is unable to enter sleep mode. What am I missing here?
