Notes 1. These registers are allocated to RAM window 0 for the CAN module (receive rules and CAN RAM test
register). When setting these registers, set the RPAGE bit in the GRWCR register to 0.
2. These registers are allocated to RAM window 1 for the CAN module (receive buffer, receive FIFO buffer,
transmit/receive FIFO buffer, transmit buffer, and transmit history data). When setting these registers, set the
RPAGE bit in the GRWCR register to 1.
