CADCSRB – CC-ADC Control and Status Register B
• Bits 4:3 – CADAS1:0: CC-ADC Accumulate Current Select
The CADAS bits select the conversion time for the Accumulate Current output as shown in the
Table
Table 19-1.
Note:
• Bits 2:1 – CADSI1:0: CC-ADC Current Sampling Interval
The CADSI bits determine the current sampling interval for the Regular Current detection as
shown in the
Table 19-2.
Notes:
• Bit 0 – CADSE: CC-ADC Sampling Enable
When the CADSE bit is written to one, the ongoing CC-ADC conversion is aborted and the CC-
ADC enters Regular Current detection mode.
• Bits 7, 3 – Reserved
These bits are reserved in the ATmega16HVB/32HVB and will always read as zero.
• Bit 6 – CADACIE: CC-ADC Accumulate Current Interrupt Enable
When the CADACIE bit is set (one), and the I-bit in the Status Register is set (one), the CC-ADC
Accumulate Current Interrupt is enabled.
