MSCAN
22.3.2
This section describes in detail all the registers and register bits in the MSCAN module. Each description
includes a standard register diagram with an associated figure number. Details of register bit and field
function follow the register diagram, in bit order. All bits of all registers in this module are completely
synchronous to internal clocks during a register read.
22.3.2.1
This register provides for various control of the MSCAN module as described below.
Read: Anytime
Write: Anytime when out of initialization mode; exceptions are read-only RXACT and SYNCH, RXFRM
(which is set by the module only), and INITRQ (which is also writable in initialization mode).

RXFRM
MSCAN Control 0 Register (CANCTL0)
The CANCTL0 register (except the WUPE, INITRQ, and SLPRQ bits) is
held in the reset state when initialization mode is active (INITRQ = 1 and
INITAK = 1). The CSWAI, TIME, WUPE, and SLPRQ bits are writable as
soon as the initialization mode is complete (INITRQ = 0 and INITAK = 0).
Received Frame Flag bit is read and clear only. It is set when a receiver has received a valid message
correctly, independently of the filter configuration. After set, it remains set until cleared by software or reset.
Clear by writing 1 to the bit. This bit is not valid in loop-back mode.
0 No valid message was received since last clearing this flag.
1 A valid message was received since last clearing of this flag.
Receiver Active Status bit indicates MSCAN is receiving a message. The receiver front end controls the flag.
This bit is not valid in loop-back mode.
0 MSCAN is transmitting or idle
1 MSCAN is receiving a message (including when arbitration is lost).
Synchronized Status bit indicates whether MSCAN is synchronized to the CAN bus and can participate in the
communication process. It is set and cleared by MSCAN.
0 MSCAN is not synchronized to the CAN bus.
1 MSCAN is synchronized to the CAN bus.
