Manually Triggered Conversion
(Command Code = 0000)
Before beginning a manual conversion, ensure the
scan mode bit in the setup register is zero, because a
logic 1 disables manual conversions. The address bits
in a Manually Triggered Conversion command select
the input channel for conversion (see Table 3). When
performing a differential conversion, use the even chan-
nel address (AIN0, AIN2, AIN4, AIN6); the command is
ignored if odd channel addresses (AIN1, AIN3, AIN5,
AIN7) are used for a differential conversion.
After issuing a Manually Triggered Conversion com-
mand, bring CS high to begin the conversion. To obtain
a correct conversion result, CS must remain high for a
period longer than the reference power-up time (if in
power-down mode) plus the conversion time for the
selected channel-configured conversion type (voltage
or temperature). The conversion’s result can then be
read at DOUT by issuing a Read Current Data Register
for Selected Channel command, addressing the con-
verted channel. See Table 3 for channel addresses.
