9 Programming and Calibration
9.1 Programming of the Temporary Memory of 90807
The temporary memory consists of a shift register of flip flops. It is used to search for the correct calibration
settings. Mode 1 (TC[5:0]=01h) is used for this purpose. Afterwards these settings can be put in the
permanent memory. The programming is done through the connector: you only need the application pins
(supply, ground and output). You can enable the programming by forcing the supply high enough (VCC_T).
You can input the data through the OUT pin. The data is Pulse Width modulated. At the end of the
programming, we keep OUT high until VCC has reached his normal level (VCC_N). Thereafter we disconnect
OUT. It is not necessary to do a power-down before the next settings are programmed.
