pub struct INPUT_SYNC_BYPASS_SPEC;
Expand description
There is a 2-flipflop synchronizer on each GPIO input, which protects PIO logic from metastabilities. This increases input delay, and for fast synchronous IO (e.g. SPI) these synchronizers may need to be bypassed. Each bit in this register corresponds to one GPIO.
0 -> input is synchronized (default)
1 -> synchronizer is bypassed
If in doubt, leave this register as all zeroes.
You can read
this register and get input_sync_bypass::R
. You can reset
, write
, write_with_zero
this register using input_sync_bypass::W
. You can also modify
this register. See API.
