Supply current measurement is based on 0x93[2:0] = 6 setting. These bits should be set to 6 after power- on and resets. Lower settings will increase power consumption. Crystal deviation is based on normal operation condition. Compliance to datasheet limits is assured by one or more methods: production test, characterization and/or design. 11 11 Page
