Appendix B: Register Details
instr_fetch_err 16 sro,ns
sraz,n
snsro
0x0 Indicates the AXI response that the DMAC
receives on the RRESP bus after the DMA channel
thread performs an instruction fetch:
0: OKAY response
1: EXOKAY, SLVERR, or DECERR response. This
fault is a precise abort.
reserved 15:14 sro,ns
sraz,n
snsro
0x0 read undefined
st_data_unavailable 13 sro,ns
sraz,n
snsro
0x0 Indicates whether the MFIFO did not contain the
data to enable the DMAC to perform the DMAST:
0: MFIFO contains all the data to enable the
DMAST to complete
1: previous DMALDs have not put enough data in
the MFIFO to enable the DMAST to complete.
This fault is a precise abort.
mfifo_err 12 sro,ns
sraz,n
snsro
0x0 Indicates whether the MFIFO prevented the DMA
channel thread from executing DMALD or
DMAST:
DMALD:
0: MFIFO contains sufficient space
1: MFIFO is too small to hold the data that
DMALD requires.
DMAST:
0: MFIFO contains sufficient data
1: MFIFO is too small to store the data to enable
DMAST to complete.
This fault is an imprecise abort.
reserved 11:8 sro,ns
sraz,n
snsro
0x0 read undefined
ch_rdwr_err 7 sro,ns
sraz,n
snsro
0x0 Indicates whether a DMA channel thread, in the
Non-secure state, attempts to program the CCR
registers to perform a secure read or secure write:
0: a DMA channel thread in the Non-secure state
is not violating the security permissions
1: a DMA channel thread in the Non-secure state
attempted to perform a secure read or secure
write. This fault is a precise abort.
