Hall Sensor And Encoder Interface (Jp: 20, 21, 22, 29, 31, 33, 34) - Fujitsu MB91470 SERIES User Manual

6.7 Hall sensor and encoder interface (JP: 20, 21, 22, 29, 31, 33, 34)

JP20, JP21, JP22 These jumpers connect the Hall sensors (X8) to the input capture pins
IC0-IC2 of the MCU
JP31, JP33, JP34 These jumpers connect the encoder interface (X9) to the up/down
counter inputs AIN, BIN and ZIN
JP29 This jumper connects the up/down counter's AIN input to the Base
Timer 0 input (TIN0) for easy speed measurement in PWC mode.

If required by the encoder in use, additional pull-up resistors (R28-R30, usually 2k7) can be
mounted on the board near the encoder connector. Use standard SMD0805 chip resistors.
