18 SPE Mapper Functional Description
Table 539. F2 Monitor
18.14.6 Path User Byte F3 Monitor
The SPE mapper monitors the second path user channel in the F3 byte. The current value of the F3 byte is stored
in SPE_F3DMON0[7:0]
programmed in SPE_CNTDF3[3:0]
be identical for a number of frames, determined by SPE_CNTDF3[3:0], prior to updating SPE_F3DMON0[7:0].
Whenever the contents of the F3 byte monitor (SPE_F3DMON0[7:0]) changes, a delta bit SPE_F3DMOND

The SPE mapper maintains a history of the previous valid F3 byte in SPE_F3DMON1[7:0]

18.14.7 N1 Monitor
The SPE mapper stores the current value of the N1 byte in SPE_N1DMON[7:0]
number of consecutive frames (determined by the value programmed in bits SPE_CNTDN1[3:0]
identical N1 bytes, i.e., the 8-bit pattern must be identical for a number frames determined by the value in register
