164 / 308 page  ST7MC1/ST7MC2 164/308 MOTOR CONTROLLER (Cont’d) 10.6.6.13 Encoder Mode (IS[1:0] = 11) Figure 90 shows the signals delivered by a stand- ard digital incremental encoder and associated in- formation: – Two 90° phased square signals with variable frequency proportional to the speed; they must be connected to MCIA and MCIB input pins, – Clock derived from incoming signal edges, – Direction information determined by the rela- tive phase shift of input signals ( + or -90°). The Incremental Encoder Interface block aims at extracting these signals. As input logic is both ris- ing and falling edge sensitive (independently from TES[1:0] bits setting), resulting clock frequency is four times the one of the input signals, thus in- creasing resolution for measurements. It may be noticed that Direction bit (EDIR bit in MCRC register) is read only and that it does’nt af- fect counting direction of clocked timer (cf Section ). As a result, one cannot extract position informa- tion from encoder inputs during speed reversal. Figure 89. Tacho Capture events configured by the TES[1:0] bits Figure 90.
