Sample Program for Erasing One Block: This program uses the following registers.
R0:
ER1: Stores address used in prewrite
ER2: Stores address used in prewrite and erase-verify
ER3: Stores address used in erase-verify
ER4: Timing loop counter
R5:
R6:
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.
