RX23W Group 36. CAN Module (RSCAN)
36.2.11 Global Control Register L (GCTRL)
GMDC[1:0] Bits (Global Mode Select)
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
section 36.3.1, Global Modes. Setting the GSLPR bit to 1 in global reset mode places the CAN
module in global stop mode.
GSLPR Bit (Global Stop Mode)
Setting this bit to 1 places the CAN module in global stop mode.
Setting this bit to 0 makes the CAN module leave from global stop mode.
Do not modify this bit in global operating mode or in global test mode.
DEIE Bit (DLC Error Interrupt Enable)
When the GERFLL.DEF flag becomes 1 while the DEIE bit is 1, an interrupt request is generated. Modify this bit only in
global reset mode.
MEIE Bit (FIFO Message Lost Interrupt Enable)
When the GERFLL.MES flag becomes 1 while the MEIE bit is 1, an interrupt request is generated. Modify this bit only
in global reset mode.
THLEIE Bit (Transmit History Buffer Overflow Interrupt Enable)
When the GERFLL.THLES flag becomes 1 while the THLEIE bit is 1, an interrupt request is generated. Modify this bit
only in global reset mode.
