I would like to use the FGH100M using the WAKE and BUSY pins to achieve low power operation. There is a note in the FGH100M Hardware Design document about the BUSY pin being multiplexed (GPIO 0) and to contact Support if it is needed. What is necessary in order to use the BUSY pin to wake a host device?
BUSY pin is OUT pin for FGH100M, so I think it is the customer themselves to define how to wake the host.
Thank you for the response. From your response and the comments regarding the pin usage, it sounds like the functionality of the BUSY pin is still useable when power saving is enabled.
I thought there may some additional steps needed based on the comments I saw that indicated the need to ‘Contact Support’ for using the BUSY output.
