START = 1 : Start ISP function which indicated by ISPF[1:0].
START = 0 : no operation.
The START bit is read-only by default, software must write three specific
values 55h, AAh and 55h sequentially to the ISPFD register to enable the
START bit write attribute. That is:
ISP function. The Flash memory address should not include the ISP
service program space address. If the Flash memory address indicated
by ISPFAH and ISPFAL registers overlaps with the ISP service program
space, the Flash write and page erase function will have no effect.
