Description
1 = CAN Trx Active Mode
At Exit from Active Mode, this bit is set to ‘0’ automatically
4
LIN_WU_EN(2)
Enable wake-up by LIN
0 = disabled
1 = enabled (default)
Note:
The wake-up behavior is configurable in the Configuration Register (0x3F)
3
CAN_WU_EN (2)
CAN Receive only Mode
0 CAN Receive Only Mode disabled (default)
1 CAN Receive Only Mode enabled (CAN Trx must be activated, see CAN_ACT bit)
2
TIMER_NINT _SEL
CAN Transceiver activation
0 = CAN Trx Low Power Mode (default)
1 = CAN Trx Active Mode
At Exit from Active Mode, this bit is set to ‘0’ automatically
1
TIMER_WU _EN
Enable wake-up by LIN
0 = disabled
1 = enabled (default)
Note:
The wake-up behavior is configurable in the Configuration Register (0x3F)
0
TRIG
CAN Receive only Mode
0 CAN Receive Only Mode disabled (default)
1 CAN Receive Only Mode enabled (CAN Trx must be activated, see CAN_ACT bit)
1. Lower is the timer duration and major is the contribution of output tdON
2. For SPSB0815 and SPSB0813 either LIN, CAN or WUx must be enabled as wake-up source. For
SPSB081C devices (without LIN), the LIN_WU_EN is forced to 0. If DIR_WU2_EN is set to 0, setting
all bits 3, 4, 16 & 17 to ‘0’ is an invalid setting. If DIR_WU2_EN is set to 1, setting all bits 3, 4, 16 to ‘0’ is an
invalid setting. In case of invalid setting, all wake-up sources will be configured according to default setting
and SPI Error Bit (SPIE) in Global Status Register will be set.
