69 / 386 page  69 2467S–AVR–07/09 ATmega128 shaded region of the “SYNC LATCH” signal. The signal value is latched when the system clock 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 ½ and 1½ 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 32. 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 one system clock period. Figure 32.
