Figure 5.1. Minimum VDD Monitor Threshold vs. System Clock Frequency
Note: With system clock frequencies greater than 25 MHz, the V
monitor level should be set to the high threshold
DD
(VDMLVL = 1b in SFR VDM0CN) to prevent undefined CPU operation. The high threshold should only be used
with an external regulator powering V
directly. See Figure 9.2 on page 80 for the recommended power
DD
supply connections.
