19.4.3.1 Static Operating Mode

The static operating mode will output a fixed DC voltage as defined by DACDAT. Repeated writes will reset the timers and may prevent the DAC from reaching the other filter modes. It is not recommended to repeatedly write the same DACDAT value, as it incurs transients on the output when filters are switched. In Static mode, the filters operate in the order of Transition, Fast and Steady-State modes, as defined by Table 19-9

Table 19-9. Static Operating Mode Output Filter Timer Conditions
Output Filter Mode	Entry Condition	Exit Condition
Transition mode	Data write	TMODTIME expires
Fast mode	TMODTIME expires	SSTIME expires data write
Steady-State mode	SSTIME expires	Data write

Table 19-10. Static Mode Timer Configurations
TMODTIME	SSTIME	Result
0	0	Immediately to Steady State
0	1 to 0x3FF	Fast mode until SSTIME, Steady State (recommended)
1 to 0x3FF	1 to 0x3FF Where SSTIME > TMODTIME	Transition until TMODTIME, Fast mode until SSTIME, Steady State
