JAJSFA4D August 2015 – April 2018 LMK03328
PRODUCTION DATA.
The NVMUNLK register provides a rudimentary level of protection to prevent inadvertent programming of the on-chip EEPROM.
Bit # | Field | Type | Reset | EEPROM | Description |
---|---|---|---|---|---|
[7:0] | NVMUNLK[7:0] | RW | 0x00 | N | EEPROM Prog Unlock. The NVMUNLK register must be written immediately prior to setting the NVMPROG bit of register NVMCTL, otherwise the Erase/Program cycle will not be triggered. During the EEPROM Erase/Program cycle, no I2C packets can be sent to other devices sharing the I2C bus with LMK03328 and any violations would invalidate the Erase/Program cycle. NVMUNLK must be written with a value of 0xEA. |
