Figure 11-17. Receive A End-of-Frame Pointer (RXAEFP)
Read: Anytime.
Write: Never.
The receive A end-of-frame pointer (RXAEFP) 11-bit field specifies the address offset of the last byte was
that written to the receive buffer A. The base address of receive buffer A is determined by BUFMAP.
RXAEFP is valid only while RXACIF is set.

The receive B end-of-frame pointer (RXBEFP) 11-bit field specifies the address offset of the last byte that
was written to the receive buffer B. The base address of receive buffer B is determined by BUFMAP.
RXBEFP is valid only while RXBCIF is set.
