Table 4.11 SFR Address Map (11/20)
X: Undefined
Blank spaces are all reserved. No access is allowed.
NOTES:
1. Values are obtained by setting the SLEEP bit in the C1SLPR register to “1” (sleep mode exited) after reset and supplying a clock to the CAN
module.
2. The CAN-associated registers (allocated in addresses 01E0h to 02BFh) cannot be used in M32C/87B. In M32C/87A, only CAN0-associated
registers can be used.
3. Set the PM13 bit in the PM1 register to 1 (2 wait states for SFR area) before accessing the CAN-associated registers.
