The
SYNC signal can be issued using one of two different methods:
- One of the GPIO1/2 pins can be configured via SPI
to become the SYNC input pin (address 0x234 in the digital
page)
- The synchronization command can be issued via SPI
register write (address 0x21 in the JESD page)
When using the GPIO1/2 pins for the SYNC signal input, the device also supports the option to invert the signal polarity (address 0x236 in the digital page).
