• Bits 5, 2:0 – WDP3..0: Watchdog Timer Prescaler 3, 2, 1 and 0
The WDP3..0 bits determine the Watchdog Timer prescaling when the Watchdog Timer is run-
ning. The different prescaling values and their corresponding time-out periods are shown in
Table 8-3 on page
Table 8-3.
• Bit 7 – VLMF: VLM Flag
This bit is set by the VLM circuit to indicate that a voltage level condition has been triggered (see
Table
age at V
• Bit 6 – VLMIE: VLM Interrupt Enable
When this bit is set the VLM interrupt is enabled. A VLM interrupt is generated every time the
VLMF flag is set.
• Bits 5:3 – Res: Reserved Bits
These bits are reserved. For ensuring compatibility with future devices, these bits must be writ-
ten to zero, when the register is written.
