SLASF61A January 2023 – September 2023 DAC539G2-Q1
PRODUCTION DATA
The DAC539G2-Q1 implements a register-map lock feature that prevents an accidental or unintended write to the DAC registers. The device locks all the registers when the DEV-LOCK bit in the COMMON-CONFIG register is set to 1. However, the software reset function through the COMMON-TRIGGER register is not blocked when using I2C. To bypass the DEV-LOCK setting, write 0b0101 to the DEV-UNLOCK bits in the COMMON-TRIGGER register.
