PSC Input Configuration
Filter Enable
For detailed information on the PSC, please refer to Application Note ‘AVR138: PSC Cook-
book’, available on the Atmel web site.
Each module 0, 1 and 2 of PSC has its own system to take into account one PSC input.
According to PSC Module n Input Control Register
– PMICn” on page
Each block A or B is also configured by this PSC Module n Input Control Register (PMICn).
Figure 14-10. PSC Input Module
The PSC Input Configuration is done by programming bits in configuration registers.
If the “Filter Enable” bit is set, a digital filter of 4 cycles is inserted before evaluation of the sig-
nal. The disable of this function is mainly needed for prescaled PSC clock sources, where the
noise cancellation gives too high latency.
Important: If the digital filter is active, the level sensitivity is true also with a disturbed PSC
clock to deactivate the outputs (emergency protection of external component). Likewise when
used as fault input, PSC Module n Input A or Input B have to go through PSC to act on
PSCOUTn0/1/2 outputs. This way needs that CLK
nous Output Control bit (PAOCnA/B), PSCINn input can desactivate directly the PSC outputs.
Notice that in this case, input is still taken into account as usually by Input Module System as
soon as CLK
