RstReg (Register 11)
The RstReg is used to indicate the status of command execution. The result code is listed as
follows:
Bit
Description
Default
3:0
4-bit error code
0000
0000 – No error
0001 – Cannot find the specified entry
Other – Errors
4
Command completed.
0
0 – Execution has been started but not yet completed
1 – Execution has been completed, Must check Bit[3:0],
any error occurring.
CfgReg (Register 12)
The CfgReg is used to configure the ARL functions. The bit definition of CfgReg is described as:
Bit
Description

IntSrcReg (Register 13)
The IntSrcReg is used to indicate what can cause interrupt request to CPU. The source of
interrupt is listed as:
Bit
Description

0
IntMskReg (Register 14)
The IntMskReg is used to enable an interrupt source to generate an interrupt request. The bit
definition is the same as IntSrcReg. A 1 in a bit enables the corresponding interrupt source to
generate an interrupt request once it is set.
