Action
NOP.
Write control register.
F4 = 1: temperature over 130°C.
F4 = 0: temperature under 130°C.
Read-only bit. This bit should be 0 when writing to the control register.
F3 = 1: PEC error.
F3 = 0: No PEC error. Reserved.
Read-only bit. This bit should be 0 when writing to the control register.
F2 = 1: select Register X1B for input.
F2 = 0: select Register X1A for input.
F1 = 1: enable temperature shutdown.
F1 = 0: disable temperature shutdown.
F0 = 1: soft power-down.
F0 = 0: soft power-up.
Write data in F13 to F0 to OFS0 register.
Write data in F13 to F0 to OFS1 register.
Select register for readback.
Write data in F7 to F0 to A/B Select Register 0.
Write data in F7 to F0 to A/B Select Register 1.
Block write A/B select registers.
F7 to F0 = 0: write all 0s (all channels use X2A register).
F7 to F0 = 1: write all 1s (all channels use X2B register).
F5 = 1: monitor enable.
F5 = 0: monitor disable.
F4 = 1: monitor input pin selected by F0.
F4 = 0: monitor DAC channel selected by F3:F0
(0000 = DAC0; 1111 = DAC15).
F3 = not used if F4 = 1.
F2 = not used if F4 = 1.
F1 = not used.
F0 = 0: MON_IN0 selected for monitoring (if F4 and F5 = 1).
F0 = 1: MON_IN1 selected for monitoring (if F4 and F5 = 1).
GPIO configure and write.
F1 = 1: GPIO is an output. Data to output is written to F0.
F1 = 0: GPIO is an input. Data can be read from F0 on readback.
I12
F12
data required for execution of the special function, for example
the channel address for data readback.
The codes for the special functions in Table 16 show the
addresses for data readback.
