Pg 1 Bulletin #1303181 ____________________________________________________________________________________________________ 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.
