TABLE 1
*This mode is for applications where OUT0 is not used, but CTRL0 is used as a device shutdown.
**Default Condition
CONTROL PIN 1 (CTRL1) – A multifunctional input pin that can be selected as an output enable
and/or a power-down. Its function is determined by the user-programmable control register value of
PDN1. (See Table 2.)
TABLE 2
*Default Condition
NOTE:
Both CTRL0 and CTRL1 can be configured as power-downs, they are internally “OR” connected so that
either of the control pins may be used to provide a power-down function for the whole device, subject to
appropriate settings of the PDN0 and PDN1 register bits. (See Table 3.)
