MSCAN Bus Timing Register 0 (CANBTR0)
Sleep Mode Acknowledge. This flag indicates whether the MSCAN module has entered sleep mode (see
Section 22.4.8.1, “MSCAN Sleep
Sleep mode is active when SLPRQ = 1 and SLPAK = 1. Depending on the setting of WUPE, the MSCAN
clears the flag if it detects activity on the CAN bus while in sleep mode.
0 Running.The MSCAN operates normally.
1 Sleep Mode Active.The MSCAN has entered sleep mode.
Initialization Mode Acknowledge. This flag indicates whether the MSCAN module is in initialization mode (see
Section 22.4.8.2, “MSCAN Initialization
mode request. Initialization mode is active when INITRQ = 1 and INITAK = 1. The registers CANCTL1,
CANBTR0, CANBTR1, CANIDAC, CANIDAR0–CANIDAR7, and CANIDMR0–CANIDMR7 can be written only
by the Power Architecture when the MSCAN is in initialization mode.
0 Running. The MSCAN operates normally.
1 Initialization Mode Active. The MSCAN has entered initialization mode.
Synchronization Jump Width defines the maximum number of time quanta (Tq) clock cycles (refer to
