HRESPDIS
0
By default, when CPU try to write ROM area directly, flash
interface will return ERROR response by AMBA protocol
1
Disable HRESP(error response function) of Data or System
bus (HRESP is AMBA AHB signal)
This bit only be written in AMBA mode and MSB 16-bit (bit
[31:16]) must be 0x7858
12
TESTCLK
0
TEST Clock selection (test purpose only)
Set “1” to use system bus clock instead of internal 40MHz
OSC
This bits only be written in AMBA mode and MSB 16-bit (bit
[31:16]) must be 0x7858
9
8
WAIT
This bits only be written in AMBA mode and MSB 16-bit (bit
[31:16]) must be 0x7858
00
WAIT is 00, flash access in 1 cycle (0-wait)
01
WAIT is 01, flash access in 2 cycles (1-wait)
10
WAIT is 10, flash access in 3 cycles (2-wait) – default
11
WAIT is 11, flash access in pre-fetch mode
Note)
In pre-fetch mode, OTP (0x3F0000xx~0x3F0005xx) read and
Program/Erase operation would not work correctly.
User must exit from pre-fetch mode to read OTP or
program/erase flash memory
7
CRCINIT
0
When this bit is set(‘1’), CRC register will be initialized
It should be reset again before read flash to generate CRC16
calculation
(Initial value of FMCRC is 0xFFFF)
6
CRCEN
0
CRC16 enable
CRC value will be calculated at every flash read timing
