Important Note: If the V
is selected as a reset source. Selecting the V
lized may cause a system reset. In some applications, this reset may be undesirable. If this is not desirable
in the application, a delay should be introduced between enabling the monitor and selecting it as a reset
source. The procedure for enabling the V
state is as follows:
1. Enable the V
2. If necessary, wait for the V
3. Select the V

monitor reset. See Table 5.4 for complete electrical characteristics of the V
See “Figure 5.1. Minimum VDD Monitor Threshold vs. System Clock Frequency” on page 44 for V
itor threshold level requirements.
Note: The output of the internal voltage regulator is calibrated by the MCU immediately after any reset event. The
Note: This delay should be omitted if software contains routines that erase or write Flash
memory.
output of the un-calibrated internal regulator could be below the high threshold setting of the VDD Monitor. If
this is the case and the VDD Monitor is set to the high threshold setting and if the MCU receives a non-power
on reset (POR), the MCU will remain in reset until a POR occurs (i.e., VDD Monitor will keep the device in
reset). A POR will force the VDD Monitor to the low threshold setting which is guaranteed to be below the un-
calibrated output of the internal regulator. The device will then exit reset and resume normal operation. It is for
this reason Silicon Labs strongly recommends that the VDD Monitor is always left in the low threshold setting
(i.e., default value upon POR).
When programming the Flash in-system, the VDD Monitor must be set to the high threshold setting. For the
highest system reliability, the time the VDD Monitor is set to the high threshold setting should be minimized
(e.g. setting the VDD Monitor to the high threshold setting just before the Flash write operation and then
changing it back to the low threshold setting immediately after the Flash write operation).
