Description

Flash Control Register 2

Fields

ARDSEQID

Sequence Index for AHB Read triggered Command in LUT.

ARDSEQNUM

Sequence Number for AHB Read triggered Command in LUT.

AWRSEQID

Sequence Index for AHB Write triggered Command.

AWRSEQNUM

Sequence Number for AHB Write triggered Command.

AWRWAIT

For certain devices (such as FPGA), it need some time to write data into internal memory after the command sequences finished on FlexSPI interface

AWRWAITUNIT

AWRWAIT unit

0 (AWRWAITUNIT_0): The AWRWAIT unit is 2 ahb clock cycle

1 (AWRWAITUNIT_1): The AWRWAIT unit is 8 ahb clock cycle

2 (AWRWAITUNIT_2): The AWRWAIT unit is 32 ahb clock cycle

3 (AWRWAITUNIT_3): The AWRWAIT unit is 128 ahb clock cycle

4 (AWRWAITUNIT_4): The AWRWAIT unit is 512 ahb clock cycle

5 (AWRWAITUNIT_5): The AWRWAIT unit is 2048 ahb clock cycle

6 (AWRWAITUNIT_6): The AWRWAIT unit is 8192 ahb clock cycle

7 (AWRWAITUNIT_7): The AWRWAIT unit is 32768 ahb clock cycle

CLRINSTRPTR

Clear the instruction pointer which is internally saved pointer by JMP_ON_CS. Refer Programmable Sequence Engine for details.
