11.3.2 FICP Control Register 1 (ICCR1)
The ICCR1, shown in Table 11-3, contains the 8-bit address match value field that the FICP uses to
selectively receive frames. To allow the address match value to be changed during active receive
operation, ICCR1 may be written while the FICP is enabled.
This is a read/write register. Ignore reads from reserved bits. Write zeros to reserved bits.

Bits Name Description
[31:8] reserved
[7:0] AMV
Address match value.
The 8-bit value used by receiver logic to compare to address of incoming frames. If AME=1
and AMV matches the address of the incoming frame, store the frame address, control,
and data in receive FIFO. If the address does not match, ignore the frame and search for
the next preamble.
The broadcast address 0xFF in the incoming frame always generates a match.
