Customer Actions Needed:
Devices with firmware modifying flash write or erase operatins using the FLASHCTRL module must
ensure that the VMON0 supply monitor is enabled as a reset source prior to executing the flash
modification operation.
Devices with date codes later than 1311 will behave as described in revision 1.0 of the
SiM3U1xx/SiM3C1xx Reference Manual. These devices will ignore flash write and erase operations if the
VMON supply monitor (VMON0) is not enabled as a reset source.
Please see your Silicon Labs sales representatives if you have questions. A list of Silicon Labs sales
