DS90UB947-Q1: How to pass the PWM signal from DS90UB947-Q1 to DS90UB948-Q1?

Hello,
GPIO[3:0] may be used as general purpose IOs in forward channel (outputs) on the DS90Ux948-Q1 when paired with DS90Ux947-Q1. Please see section 8.3.9.1 in the 948 datasheet.
Regards,

Hi Went,

You should be able to use GPIO[0:3] for this.

Please refer to this thread on setting the registers up to pass through signals between the DS90UB947 and the DS90UB948: e2e.ti.com/.../597339
