Chapter 10 Freescale’s Scalable Controller Area Network (S12MSCANV2)
The IDHITx indicators are always related to the message in the foreground buffer (RxFG). When a
message gets shifted into the foreground buffer of the receiver FIFO the indicators are updated as well.
10.3.2.13 MSCAN Reserved Registers
These registers are reserved for factory testing of the MSCAN module and is not available in normal
system operation modes.
Read: Always read 0x0000 in normal system operation modes
Write: Unimplemented in normal system operation modes
10.3.2.14 MSCAN Receive Error Counter (CANRXERR)
This register reflects the status of the MSCAN receive error counter.
Read: Only when in sleep mode (SLPRQ = 1 and SLPAK = 1) or initialization mode (INITRQ = 1 and
INITAK = 1)
Write: Unimplemented
