disables averaging. For example, if AVGON = 1,
NAVG[1:0] = 00, NSCAN[1:0] = 11 and SCAN[1:0] =
10, 16 results are written to the FIFO, with each result
being the average of four conversions of channel N.
DAC Select Register
Write a command byte 0001XXXX to the DAC select
register (as shown in Table 9) to set up the DAC inter-
face and indicate that another word will follow. The last
4 bits of the DAC select register are don’t-care bits. The
word that follows the DAC select-register command
byte controls the DAC serial interface. See Table 20
and the
DAC Serial Interface section.
Reset Register
Write to the reset register (as shown in Table 11) to
clear the FIFO or reset all registers (excluding the DAC
and GPIO registers) to their default states. When the
RESET bit in the reset register is set to 0, the FIFO is
cleared. Set the RESET bit to one to return all the
device registers to their default power-up state. All reg-
isters power up in state 00000000, except for the setup
register that powers up in clock mode 10 (CKSEL1 = 1
and REFSEL1 = 1). The DAC and GPIO registers are
not reset by writing to the reset register. Set the SLOW
bit to one to add a 15ns delay in the DOUT signal path
to provide a longer hold time. Writing a one to the
SLOW bit also clears the contents of the FIFO. Set the
FBGON bit to one to force the bias block and bandgap
reference to power up regardless of the state of the
DAC and activity of the ADC block. Setting the FBGON
bit high also removes the programmed wake-up delay
between conversions in clock modes 01 and 11.
Setting the FBGON bit high also clears the FIFO.
GPIO Command
Write a command byte to the GPIO command register
to configure, write, or read the GPIOs, as detailed in
Table 12.
Write the command byte 00000011 to configure the
GPIOs. The eight SCLK cycles following the command
byte load data from DIN to the GPIO configuration reg-
ister in the MAX1020. The 16 SCLK cycles following the
command byte load data from DIN to the GPIO configu-
ration register in the MAX1057/MAX1058. See Tables
13 and 14. The register bits are updated after the last
