C8051F50x/F51x
Note: With system clock frequencies greater than 25 MHz, the VDD monitor level should be set to the high threshold
44
with an external regulator powering VDD directly. See Figure 10.2 on page 85 for the recommended power
supply connections.
(VDMLVL = 1b in SFR VDM0CN) to prevent undefined CPU operation. The high threshold should only be used
