7.2
7.2.1
In order to erase a block of data EEPROM, the
NVMADRU and NVMADR registers must initially
point to the block of memory to be erased. Configure
NVMCON for erasing a block of data EEPROM, and
set the ERASE and WREN bits in the NVMCON
register. Setting the WR bit initiates the erase, as
shown in
EXAMPLE 7-2:
7.2.2
The TBLPAG and NVMADR registers must point to
the block. Select erase a block of data Flash, and set
the ERASE and WREN bits in the NVMCON register.
Setting the WR bit initiates the erase, as shown in
Example
EXAMPLE 7-3:
DS70141F-page 58
; Select data EEPROM block, ERASE, WREN bits
; Start erase cycle by setting WR after writing key sequence
; Erase cycle will complete in 2mS. CPU is not stalled for the Data Erase Cycle
; User can poll WR bit, use NVMIF or Timer IRQ to determine erasure complete
; Select data EEPROM word, ERASE, WREN bits
; Start erase cycle by setting WR after writing key sequence
; Erase cycle will complete in 2mS. CPU is not stalled for the Data Erase Cycle
; User can poll WR bit, use NVMIF or Timer IRQ to determine erasure complete
