CHAPTER 2
Additional information
2.1
Flash Interface
2.1.2 Flash Control Status Register (FMCS)
Bit 7: FACCEN: Controls read access mode to flash
0: Synchronous read access using ATDIN and EQIN signals - recommended setting
1: Asynchronous read access
Bits 6,5: reserved
when writing to these bits always write "11"
Bit 4: RDYEG:
When the auto algorithm of flash memory is finished, this bit is set to '1'.
This bit is cleared by reading it.
0: Auto algorithm not yet finished
1: Auto algorithm finished
Bit 3: RDY:
The state of auto algorithm
0:The state of the auto algorithm is WRITE/READ. Can't accept WRITE/READ/DELETE.
1:It is possible to accept WRITE/READ/DELETE.
Bit 2: RDYI: Reserved bit
Bit 1: WE: This bit is used to control writing and reading to flash memory in CPU mode
0: writing to flash memory is disabled, read access is 32 bit wide
1: writing enabled, read access 16 bit wide, auto algorithm can be used
This bit can only be written to if RDY is 1.
Bit 0: LPM:
0: normal mode
1: low power mode, can be used when CPU frequency is below 5 MHz
