Sample Program for Programming One Byte: This program uses the following registers.
R0:
R1:
ER2: Stores the address to be programmed as long word data. Valid addresses are H'00000000 to
R3H: Stores data to be programmed as byte data
R4:
E4:
R5:
E5:
Arbitrary data can be programmed at an arbitrary address by setting the address in ER2 and the
data in R3H.
The values of #a, #b, and #g depend on the clock frequency. They can be calculated as indicated
under table 19.9.
