13.3. Flash Access Registers
The CP2200 Flash is accessed through the registers in Table 17. See the register tables following Table 17 for
detailed register descriptions
Register 59. FLASHSTA: Flash Status Register
Table 19. Flash Access Register Summary
Register
Long Name
Address
Description
FLASHSTA
Flash Status
0x7B
Used to determine the status of a Flash write
or erase operation.
FLASHKEY
Flash Lock and Key
0x67
Write-only register allowing the host to
unlock the Flash for writing or erasing.
FLASHADDRH
FLASHADDRL
Flash Address Register High and
Low Bytes
0x69
0x68
16-bit Address used for Flash operations.
FLASHDATA
Flash Read/Write Data Register
0x06
Data register used for writing or reading a
single byte of Flash.
FLASHAUTORD
Flash AutoRead Data Register
0x05
Data register used for reading a block of
sequential data stored in Flash. Each read
from this register increments the Flash
address register by 1.
FLASHERASE
Flash Erase
0x6A
Initiates a Flash erase operation.
Note: To determine when a Flash operation completes, the FLBUSY bit should be polled or software should
wait for the Flash Write/Erase Operation Complete Interrupt to occur.
Bits 7–4: UNUSED. Read = 0000b, Write = don’t care.
Bit 3:
FLBUSY: FLASH Busy Indicator
This bit indicates when a FLASH write or erase operation is in progress.
0: FLASH is idle.
1: FLASH write/erase operation is currently in progress.
Bit 2:
Reserved.
Bit 1:
FLWRITE: FLASH Write
0: The last Flash operation completed was not a Flash write.
1: The last Flash operation completed was a Flash write.
Bit 0:
FLERASE: FLASH Erase
0: The last Flash operation completed was not a Flash erase.
1: The last Flash operation completed was a Flash erase.
