Sample Program for Erasing Multiple Blocks: This program uses the following registers.
R0, R6: Specifies blocks to be erased (set as explained below)
R1H:
R1L:
ER2:
ER3:
ER4:
ER5:
E0, E1: Timing loop counter
E6:
Arbitrary blocks can be erased by setting bits in R6.
A bit map of R6 and an example setting for erasing specific blocks are shown next.
Bit
R6
Example: to erase blocks LB2, SB7, and SB0
Bit
R6
Setting
R6 is set as follows:
The values of #a, #c, #d, #e, #f, #g, and #h in the program depend on the clock frequency. They
can be calculated as indicated in tables 19.9 and 19.10.
For #RAMSTR in the program, substitute the starting destination address in RAM, to be used
when this program is moved from flash memory into RAM.
