CPCLK — Charge Pump Clock Source
The CPCLK bit is a read/write bit that controls the source of the clock
for the charge pump. When the CPCLK bit is set, the charge pump is
driven by the PH2 bus clock. When the CPCLK bit is cleared, the
charge pump is driven from an internal ring oscillator. The CPCLK bit
is cleared when the device is in reset.
In systems where the desired PH2 clock rate is below 1 MHz, the
CPCLK bit should be cleared to enable the internal ring oscillator.
Otherwise, the charge pump does not attain sufficient program/erase
voltage because the clock source is too slow.
CPEN — Charge Pump Enable
The CPEN bit is a read/write bit to control the on-chip charge pump
for programming and erasure of the Personality EEPROM. This
charge pump is only intended for use at VDD supply voltages
above 3.0 Vdc. The charge pump is activated when both the CPEN
bit is set and one of the program or erase bits is also set (PEPGM,
PEBYTE, or PBULK). The charge pump supplies the required
programming voltage to the Personality EEPROM array. Once
activated, and after startup time tCP, the charge pump continues to
operate until all the program and erase bits are cleared.
NOTE:
If the personality EEPROM is read while the CPEN bit is set, the data is
unknown.
