goes low. It is clocked into the PINxn Register at the succeeding positive clock edge. As indi-
cated by the two arrows t
pd,max and tpd,min, a single signal transition on the pin will be delayed
between and 1- system clock period depending upon the time of assertion.
When reading back a software assigned pin value, a nop instruction must be inserted as indi-
cated in Figure 24. The out instruction sets the “SYNC LATCH” signal at the positive edge of the
clock. In this case, the delay t
pd through the synchronizer is 1 system clock period.
