Description
Clear Halt request (Initial value)
Halt mode transition request
Bit 0 — Reset Request (MCR0): Controls resetting of the RCAN-ET module. When this bit is
changed from ‘0’ to ‘1’ the RCAN-ET controller enters its reset routine, re-initialising the internal
logic, which then sets GSR3 and IRR0 to notify the reset mode. During a re-initialisation, all user
registers are initialised.
RCAN-ET can be re-configured while this bit is set. This bit has to be cleared by writing a ‘0’ to
join the CAN bus. After this bit is cleared, the RCAN-ET module waits until it detects 11
recessive bits, and then joins the CAN bus. The Baud Rate needs to be set up to a proper value in
order to sample the value on the CAN Bus.
After Power On Reset, this bit and GSR3 are always set. This means that a reset request has been
made and RCAN-ET needs to be configured.
The Reset Request is equivalent to a Power On Reset but controlled by Software.
