AWR2243: SPI host intr pull down resistor

Part Number: AWR2243
Other Parts Discussed in Thread: AM2732

Tool/software:

Hi team,

I notice there are 2 resistors on our TIDA020047.

R160 is a pull down resistor for FE1_SPI_IRQ and we can see there are still some pull down resistors before the same input of AM2732.

Why we have 2 pull down resistors for this same signal?

Regards,

Shawn

    Hello,

    Only one pulldown is required. The two boards were designed separately and thus each board put a pulldown on this signal. If you are designing your own board you can just use one pulldown.
