This register provides visibility into the data FIFO for Channel X in the SiI3114. The data FIFO is organized as a
four byte-wide x 64 deep memory array. There are separate write and read pointers for each of the byte slices.
This register is used for hardware debugging purposes only. The register bits are defined below.
Bit [31:24]: FIFO Byte 1 Wr Pointer (R). This bit field provides the write pointer for Byte 1.
Bit [23:16]: FIFO Byte 1 Rd Pointer (R). This bit field provides the read pointer for Byte 1.
Bit [15:08]: FIFO Byte 0 Wr Pointer (R). This bit field provides the write pointer for Byte 0.
Bit [07:00]: FIFO Byte 0 Rd Pointer (R). This bit field provides the read pointer for Byte 0.
FIFO Pointers2– Channel X
Address Offset: 6CH / 7CH / 26CH / 27CH
Access Type: Read Only
