______________________________________________________________________________________
Data Registers
The data results from conversions or keypad scans are
held in the data registers of the MAX1233/MAX1234.
During power-up, all of these data registers with the
exception of the DAC data register default to 0000H.
The DAC register defaults to 1000H.
Analog Input Data Registers
Table 30 shows the format of the X, Y, Z1, Z2, BAT1,
BAT2, AUX1, AUX2, TEMP1, and TEMP2 data registers.
The data format for these registers is right justified
beginning with bit 11. Data written through the serial
interface to these registers is not stored.
Keypad Data Registers
Table 31 shows the formatting of the keypad data regis-
ters, while Tables 32, 33, and 34 provide individual reg-
ister bit descriptions. These registers have the same
format as the keypad mask register. Each bit repre-
sents one key on the keypad. Table 35 shows a map of
a 16-key keypad. Data written through the serial inter-
face to these registers is not stored.
