4.10 Digital Inputs and GPIO Signal Pins
The four GPIO signals on the EVM can be measured on the J6 header. The J6 header also includes most
of the digital inputs to the AMC7834 device — these inputs include Sleep1, Sleep2, ALARMOUT, RESET,
DACTRIG, and DIGTEST. A signal description of the J6 header is provided in
Table 12 .
