Talk:Fex Guide

I'm seeing some tags that aren't mentioned in the [Fex Guide] - sb_pwm[n] and pwm_gpio. Where can we find documentation on these tags?

Seen in pcdunio.fex

[sb_pwm0]

pwm_gpio = port:PH06<1>

[sb_pwm1]

pwm_gpio = port:PB02<2>

[sb_pwm2]

pwm_gpio = port:PI03<2>

[sb_pwm3]

pwm_gpio = port:PH05<1>

[sb_pwm4]

pwm_gpio = port:PI10<1>

[sb_pwm5]

pwm_gpio = port:PI12<1>
