Sample Program for Programming One Byte: This program uses the following registers.
R0H: Specifies blocks to be erased.
R1H: Stores data to be programmed.
R1L: Stores data to be read.
R3:
R4:
R5:
R6L: Used for program-verify fail count.
Arbitrary data can be programmed at an arbitrary address by setting the address in R3 and the data
in R1H.
The setting of #a and #b values depends on the clock frequency. Set #a and #b values according to
tables 19.9 (1) and (2).

Stores address to be programmed. Valid addresses are H'0000 to H'7FFF.
Sets program and program-verify timing loop counters, and also stores register setting
value.
Sets program timing loop counter.
