β¨ rza1_pin_reset β¨
okay so bestie, welcome to the Kernel API Manual π
this little cutie lives in rza1_pin_reset(9) and honestly? it's giving "factory reset but make it pinctrl" π
πΈ NAME πΈ
rza1_pin_reset β reset a pin to default initial state π«Ά
β SYNOPSIS β
void rza1_pin_reset (struct rza1_port *port , unsigned int pin );
like, that's the whole vibe. void return, no notes, no drama π
π¦ ARGUMENTS π¦
portβ the port where the pin sits on, iykyk πpinβ the pin offset, literally just where it's at in there β¨
π DESCRIPTION π
so what this does is reset the pin state, which means it disables the input buffer and the bi-directional control, and then it configures the pin as an input port. slay. π
but bestie, hear me out, here's the catch π β the pin is now configured with direction as input but with the input buffer disabled. which implies... the pin value cannot be read in this state π like it's input-coded but you can't actually peek at it. no cap, that's just how it is.
π¨ lowkey important: don't go reading from a reset pin expecting data, because the input buffer being off means there's literally nothing to read. the vibe check fails. π
