5 RSVD R 1'b1 If this bit is written to it must be a 1
4 RSVD R 1'b0 Reserved
3 WD_EN R/X/U 1’b1 WD_EN: Watchdog Enable
0 = Disabled
1 = Enabled
2 DEVICE_RESET R/WC 1'b0 DEVICE_RESET: Device Reset
0 = Current configuration
1 = Device resets to default
NOTE: Same function as RST pin
1 SWE_DIS R/W 1'b0 SWE_DIS: Sleep Wake Error Disable:
0 = Enabled
1 = Disabled
NOTE: This disables the device from starting the four minute timer when coming out of sleep mode on a wake event. If this is enabled a SPI read or write must take place within this four minute window or the device will go back to sleep. This does not disable the function for initial power on or in case of a power on reset.
0 TEST_MODE_CONFIG R/W 1'b0 Test Mode Configuration
0 = Phy Test with TXD/RXD_INT_PHY and EN_INT are mapped to external pins
1 = CAN Controller test with TXD/RXD_INT_CAN mapped to external pins

NOTE

  • The Mode of Operation changes the mode but will read back the mode the device is currently in.
  • When the device is changing the device to normal mode a write of 0 to CCCR.INIT is automatically issued and when changing from normal mode to standby or sleep modes a write of 1 to CCCR.INIT is automatically issued.
  • When GPIO1 is configured as a GPO for interrupts the interrupts list represent the following and are active low:
    • 00: SPI Fault Interrupt. Matches SPIERR if not masked
    • 01: MCAN_INT:1 m_can_int1.
    • 10: Under Voltage or Thermal Event Interrupt: Logical OR of UVCCOUT, UVSUP, UVVIO, TSD faults that are not masked.
  • When GPIO1 is configured as a GPO for interrupts the interrupts list represent the following and are active low:
    • 00: SPI Fault Interrupt. Matches SPIERR if not masked
    • 01: MCAN_INT:1 m_can_int1.
    • 10: Under Voltage or Thermal Event Interrupt: Logical OR of UVCCOUT, UVSUP, UVVIO, TSD faults that are not masked.
  • nWKRQ pin defaults to a push-pull active low configuration based off an internal voltage rail. When configuring this to work off of VIO the pin becomes and open drain output and a external pull up resistor to the VIO rail is required.
