Parameter
Frequency
Voltage
Time
Note that the program time depends on the
configuration of system clock frequency.
If the system clock frequency is out of IAP range,
user need to change F
configuring CKCFG SFR.
The first byte contains CFGWD
May be used to store user ID, or checksum, etc.
Only the full chip erase function of ISP can erase this
region.
