SDN[7:0] = ³ NCP5680 is in Shut Down mode, all the
LED are switched to the OFF state, the previously
programmed parameters are stored into their respective
registers. The Vout voltage is no longer controlled by the
chip and the SuperCap is disconnected from the Vbat. The
SuperCap voltage bias is maintained until the Vout voltage
is below 2 V.
CONFIG0[7..0] Configuration register $01
Although the third byte could carry any data when an
SDN command is transmitted, it is preferred to force all the
8 bits to zero. Consequently, a typical shut down command
shall be: $I2C Address − $00 − $00.
Note: there is no internal structure to rapidly discharge the
SuperCap: it is up to the external circuit to take whatever
action is necessary to cope with the end application.

TPLGT: activate the 200 ms time out associated to the
Picture Light function.
TPLGT = 0 ³ the 200 ms is de−activated
TPLGT = 1 ³ the 200 ms time out is activated and apply
to the Picture Light only.
Note: the 200 ms time out is automatically asserted when
the TILED current is higher than 100 mA.
