R
1
Memory wait states for the slow clock domain
('clk_slow'). The number of wait states is expressed in
'clk_hf' clock domain cycles.
8:9
FAST_WS
RW
R
0
Memory wait states for the fast clock domain
('clk_fast'). The number of wait states is expressed in
'clk_hf' clock domain cycles.

17
ECC_AUTO_CORRECT
RW

1
HW ECC autocorrect functionality:
'0': Disabled.
'1': Enabled. HW automatically writes back SRAM with
corrected data when a recoverable ECC error is
detected.
18
ECC_INJ_EN
RW
R
0
Enable error injection for system SRAM 0.
When '1', the parity (ECC_CTL.PARITY) is used when
a full 32-bit write is done to the
ECC_CTL.WORD_ADDR word address of system
SRAM 0.
