Reserved
These bits are always read as 0. The write value should
always be 0.
22
STARY
0
R/W
Status Address Ready
0: HACCSAR (status address) is not ready.
1: HACCSAR (status address) is ready.

R/W
Status Data Ready
0: HACCSDR (status data) is not ready.
1: HACCSDR (status data) is ready.

PLRFRQ
0
R/W
PCML RX Request
0: PCML RX data is not ready.
1: PCML RX data is ready and must be read. In DMA
mode, reading HACPCML automatically clears this
bit to 0.
19
PRRFRQ
0
R/W
PCMR RX Request
0: PCMR RX data is not ready.
1: PCMR RX data is ready and must be read. In DMA
mode, reading HACPCMR automatically clears this
bit to 0.
18 to 14
⎯
All
0
R
Reserved
These bits are always read as 0. The write value should
always be 0.
13
PLRFOV
0
R/W
PCML RX Overrun
0: No PCML RX data overrun has occurred.
1: PCML RX data overrun has occurred because the
HAC has received new data from slot 3 before PCML
data is not read out.
12
PRRFOV
0
R/W
PCMR RX Overrun
0: No PCMR RX data overrun has occurred.
1: PCMR RX data overrun has occurred because the
HAC has received new data from slot 4 before PCMR
data is not read out.
