ISP Description in more detail
MG82FE(L)308/316 does not make use of idle-mode to perform ISP operation. Instead, it creates CPU wait-state
to release flash memory for ISP control circuit use. Once ISP run over, CPU will be waken-up and advanced to
the instruction which follows the previous instruction that invokes ISP activity. During ISP operation, interrupt
service is also blocked until ISP run over.
ISP control circuit has a built-in timer for timing sequence control. It is referred from OSC frequency and defined
by CKCON2.XCKS[4:0] to get the accuracy erase/program timing.
