OPT9221: Pinfunction

Julian Wagner

Part Number: OPT9221

Hello everyone,

I am not sure what the funtions of "ILLUM_SW_1, ILLUM_SW_2 and ILLUM_FB" are. They remain unused in the reference design.
Also what is the TFC doing with the PMU interrupt signal? Is it able to control the PMU?
Could somebody elaborate a little bit?

Thank you and best regards,

Julian

Hi Julian,

ILLUM_SW_1, ILLUM_SW_2 are currently unused in the TFC as well as the reference design. The functionality of these pins is not supported.
PMU interrupt is also currently an unused connection. All PMU control is expected to be done by the FX2 or equivalent controller.

Regards,
Subhash
