Section 6 ROM
Sample Program for Erasing Multiple Blocks
This program uses the following registers:
R0:
R1H: Used to test bits 8 to 11 of R0. Stores read data; used in dummy write.
R1L: Used to test bits 0 to 11 of R0.
R2:
R3:
R4:
R5:
R6L: Used for prewrite-verify and erase-verify fail count.
Arbitrary blocks can be erased by setting bits in R0. R0 settings should be made by writing with a
word transfer instruction.
A bit map of R0 and a sample setting for erasing specific blocks are shown below.
Note: Bits 15 to 12 should be cleared to 0.
Example: To erase blocks LB2, SB7, and SB0
R0 is set as follows:
The values of #a, #b, #c, #d, and #e in the program depend on the operating frequency. They
should be set as indicated in tables 6.11 and 6.12.
