LOGIC COMMANDS AND REGISTERS
Figure 11. Approximate ADC Conversion Timing
Figure 12. Request AN0 Command and Response Format
REQUEST AN1 COMMAND AND RESPONSE
This command causes the analog voltage on the AN1 pin
to be measured and converted by the on-chip 10-bit ADC.
The approximate timing for the conversion following this
command is shown in Figure 11, page 20. The response to
this command depends on the format in which the command
was sent. The sensor data is sent in the format shown in
The 33784 will only act on this command if the address bits
in the command match the address that the device was
initialized with. If the addresses do not match, the device will
do nothing and no response will be generated.
