Since programming/erase operations (including emulation by RAM) have priority when a high
level is input to the FWE pin, disable all interrupt requests, including NMI.
With on-board programming, program to 32-byte programming unit blocks one time only.
Program to 128-byte programming unit blocks one time only even in the PROM mode. Erase
all the programming unit blocks before reprogramming.
Bus release must also be disabled.
