I am using a Teensy 3.6 with I2C enabled for pins 18/19 which makes sense to have pullups, but I can't seem to disable the pullups on pins 37/38 (A18_PWM_SCL1/A19_PWM_SDA1).
I know there are pullups because I set the pins to INPUT setting in order to measure an analog voltage level and I am seeing the pin affect the voltage measurement due to the pullup.
Does anybody know of a low level command I can use to disable pullups for specific pins manually?
I can provide my full code if necessary, but I would prefer not to.
Thanks.
