Register Name
Rx FIFO address range:- The AHB master can read from and write
into these addresses (For Debug purposes only). The FIFO operation
is performed only when the access is made to the below mentioned
Memory Mapped Area for Rx FIFO.
Tx FIFO address range:- The AHB master can read from and write
into these addresses (For Debug purposes only). The FIFO operation
is performed only when the access is made to the below mentioned
Memory Mapped Area for Tx FIFO.
Memory Mapped Area for Rx FIFO. AHB can only Write into this
address. A write into this address range results in a write to the Rx
FIFO wherever the write pointer points. If Rx FIFO is full, AHB write
request will result in HREADY low, unless space is there for the write
operation.
(Please Note: The write(burst or single write) should start from
address 0x9000_4080 only.)
Memory Mapped Area for Tx FIFO. AHB can only Read from this
address. A read from this address range results in a read from the top
of the Tx FIFO. If Tx FIFO is empty, AHB Read request will result in
HREADY low, unless some data is available for reading.
(Please Note: The read(burst or single read) should start from
address 0x9000_40C0 only.)
38.4.3 Register descriptions
38.4.3.1 Module Configuration Register (RLE_DEC_MCR)
The RLE_DEC_MCR holds configuration data associated with RLE_DEC operation. This register can be
accessed with 8-bit, 16-bit and 32-bit wide operations.
