2548E–AVR–07/06
BPDUV – Battery Protection Deep Under Voltage Register
Table 22-6.
• Bit 7:6 – Res: Reserved Bits
These bits are reserved bits in the ATmega406 and will always read as zero.
• Bits 5:4 – DUVT1:0: Deep Under-voltage Timing
These bits set the Deep Under-voltage Protection delay.
Table 22-7.
• Bits 3:0 – DUDL3:0: Deep Under-voltage Detection Level
These bits set the Deep Under-voltage detection level.
