FLASH_Write_DoWrite

FLASH_Read4

sub procedure FLASH_Write_DoWrite()

Description Commits the FLASH write operation.
Parameters None.
Returns

Nothing.

The block to be written to must be erased first, either from the user code FLASH_Erase32, or during 

the programming of MCU. Please note that block size that is to be erased is different from the one that 

can be written with this function!

This function is used as a part of the Flash write sequence, therefore FLASH_Write_Init and certain 

number of FLASH_Write_Loadlatch4 or FLASH_Write_Loadlatch4_Compact function calls must be 

made before this one. 

This function is to be called once, at the and of the FLASH write sequence.

const  iArr  as word[8] = (“m”, “i”, “k”, “r”, “o”, “E”, “l”, “e”)

dim ptr_data as word

  ...

  ptr_data = @iArr

  FLASH_Write_Init(0x006100, ptr_data)

  FLASH_Write_Loadlatch4()

  FLASH_Write_Loadlatch4()

  FLASH_Write_DoWrite()

None.

sub  procedure  FLASH_Read4(dim  flash_address  as  longint,  dim  write_to  as 

word)

Description Reads one latch row (4 instructions, 8 addresses) in the “regular” mode.
Parameters - 

address

: starting address of the FLASH memory block to be read 

- 

write_to

: starting address of RAM buffer for storing read data 

Starting address of RAM buffer for storing read data.

Nothing.

dim flash_address as longint

    cArr         as word[4]

    ptr_data     as word

...

flash_address = 0x006000

ptr_data = @cArr

FLASH_Read4(flash_address, ptr_data)

The user should take care of the address alignment  (see the explanation  at the beginning  of this 

page).
