EraseEepromBank
MOTOROLA
Prototype:
This static function is called to erase a bank of emulated EEPROM. If the
EEPROM bank size is less than or equal to the size of a flash sector, one sector
is erased. If the EEPROM bank size is greater than the flash sector size, then
as many sectors as required are erased. Each sector takes approximately
20ms. Interrupts are masked if IRQ_DURING_PROG is not defined. This
function is not callable by the application.
