Register Description
ATmega8HVA/16HVA
BGCCR – Bandgap Calibration C Register
Figure 21-1. Reference Circuitry
• Bit 7 - BGD: Bandgap Disable
Setting the BGD bit to one will disable the bandgap voltage reference. This bit must be cleared
(zero) before enabling CC-ADC, V-ADC or Battery Protection, and must remain unset (zero)
while either of these modules are enabled.
• Bit 6 – Res: Reserved Bit
This bit is reserved for future use.
• Bit 5:0 – BGCC5:0: BG Calibration of PTAT Current
These bits are used for trimming of the nominal value of the bandgap reference voltage. These
bits are binary coded. Minimum VREF: 000000, maximum VREF: 111111. Step size approxi-
mately 2 mV.
Updating the BGCC bits will affect both the regulator output voltage and the BOD detection
level. The BOD will react quickly to the new detection level, while the voltage regulator will adjust
the output voltage more slowly due to the external reservoir capacitor. Therefore, if the value is
increased more than a certain step size, the new BOD level may rise above the regulator output
voltage, and a false BOD reset will occur. It is recommended that the BGCC bits are updated
with a step size of 1. To allow the voltage regulator to reach the new level between each step, a
delay of 20 µs should be added between each update of the BGCC values .
