2.2 Signal Definitions of J6 (10-Pin Male Connector Socket)
The AMC7832EVM includes a 20-pin connector socket used to communicate between the EVM and the
SDM-USB-DIG platform. Although the I
2
C pins are brought out to the J12 header, the I
2
C communication
lines (I2C_SCL and I2C_SDA) are not used. The pin out of the J6 connector is shown in Table 3 .
