The rotary encoder switch function.
As figure 1 shows, the rotary encoder switch circuit is consisted of Phase detection, Interrupt
generation, Up/down counter, Direction latch and Parallel-in serial-out shift register.
Fig.1 The Rotary Encoder Switch Circuit
1) Phase detection
1-1) Clockwise
The input A and B have a chattering absorption circuit of 620ns (typ.). When signal A and B input
as fig. 2, the phase detection circuit outputs UP signal after the chattering absorption period. At
this time, the output INT also goes to high level, so this signal can be used as an interrupt. The
INT stays High level until the switch data-output mode is selected.
