The GFILT field in the RCFG2 register contains the number of SYSCLKS that the received serial data input is filtered by. The glitch filter can cause a delay up to GFILT SYSCLKS, but this is usually negligible in terms of TT resolution.
In Figure 42-12, the GFILT is programmed to be 5. For every change on the receive input that is less than or equal to this value, the change is filtered out. The number of clock cycles per tick period is normally much larger than GFILT.
