A/D Converter
The integrated 8-bit flash A/D converter is a buffered device. Each
write to CAL causes: 1) the result of the previous conversion to be
latched and made readable at CAL, and 2) the A/D converter to start
digitizing its current input. Consequently, it takes 301 writes to
CAL in order to digitize the 300 cells of a row.
