Meaning
RESET Value:
- DMAC is controlled by HOLD bit
- Little Endian
- Default Priority Scheme
- MFP configured as LBI (not needed in
this example)
RESET Value:
Size of ring buffers: 32 entries
RESET Value:
Size of ring buffers: 32 entries
IQ Base Address for SCC1,RX
IQ Base Address for SCC1,TX
IQ Base Address for CFG
max. possible buffer of TFIFO reserved
for SCC1: 124 32-bit words
Watermark of TFIFO (SCC1 portion) is
set to 2 (example).
(As soon as less than two DWORDs are
in the central TFIFO buffer, the TFIFO
requests for more data.)
RESET Value:
Watermark of RFIFO is set to one.
(As soon as one 32-bit word is stored in
the RFIFO, the RFIFO requests for data
transfer to shared memory.
RESET Value:
Watermark of TFIFO forward threshold
(SCC1 portion) is set to one.
(As soon as at least one 32-bit word is in
the central TFIFO, the TFIFO transfers
data to SCC1 transmit FIFO.)
