THLEIE Bit
When the THLEIE bit is set to 1 and the THLES flag in the GERFLL register is set to 1, an interrupt request is
generated. Modify this bit only in global reset mode.
MEIE Bit
When the MEIE bit is set to 1 and the MES flag in the GERFLL register is set to 1, an interrupt request is
generated. Modify this bit only in global reset mode.
DEIE Bit
When the DEIE bit is set to 1 and the DEF flag in the GERFLL register is set to 1, an interrupt request is
generated. Modify this bit only in global reset mode.
GSLPR Bit
Setting this bit to 1 places the CAN module in global stop mode.
Clearing this bit to 0 makes the CAN module leave from global stop mode.
Do not modify this bit while the CAN channel is in global operating mode or global test mode.
GMDC[1:0] Bits
These bits are used to select the mode of entire CAN module (global operating mode, global reset mode, or
global test mode). For details, see 18.4.1 Global Modes. Setting the GSLPR bit to 1 in global reset mode
places the CAN module in global stop mode.
