In looking at the BCM20732 BLESB-BLE-S03 PEVB ref-des that I pulled from this forum, I've noticed that there is NO pullup on GPIO, P1. (pin 25) Yet the current datasheet for the SIP module (TRM102) (pg 11) indicates that P1 requires a 10K pullup. It notes that the pin is tied internally to the WP of the EEPROM. So is a pullup required?
Thanks

The manufacture of the module found that in some use cases that the 10K resistor was required externally to prevent errors during boot. Because we could not pin point all the use cases where it would be required, we ask that customers provide the external pull-up as a preventative measure.
