bits have been transferred (8 or 16). Once this has
occurred, the MAX1497/MAX1499 wait for the next
command byte. CS must not go high between data
transfers. If CS is toggled before the end of a write or
read operation, the device mode may be unknown.
Clock in 32 zeros to clear the device state and reset the
interface so it is ready to receive a new command byte.
On-Chip Registers
The MAX1497/MAX1499 contain 12 on-chip registers.
These registers configure the various functions of the
device and allow independent reading of the ADC
results and writing to the LED display. Table 5 lists the
address and size of each register.
The first of these registers is the status register. The 8-
bit status register contains the status flags for the ADC.
The second register is the 16-bit control register. This
register sets the LED display controls, range modes,
power-down modes, offset calibration, and the reset
register function (CLR). The third register is the 16-bit
overrange register, which sets the overrange limit of the
analog input. The fourth register is the 16-bit under-
range register, which sets the underrange limit of the
analog input. Registers 5 through 7 contain the display
data for the individual segments of the LED. The eighth
register contains the custom offset value. The ninth reg-
ister contains the 16 MSBs of the ADC conversion
result. The 10th register contains the LED data. The
11th register contains the peak analog input value. The
last register contains the lower four LSBs of the 20-bit
ADC conversion result.
