26 / 70 page Pin Description III-16 Slave Controller – ET1200 Hardware Description 3.5 Distributed Clocks SYNC/LATCH Pins, MII Management Data Table 19: DC SYNC/LATCH and MII Management pins Pin Pin No MII port used MII port used Configuration Internal PU/PD Name Dir Signal Dir Signal Dir 47 SYNC/LATCH[0] BD SYNC/LATCH[0] I/O SYNC/LATCH[0] I/O 48 SYNC/LATCH[1]/MI_DATA BD SYNC/LATCH[1] I/O MI_DATA BD SYNC/LATCH[x]/MI_DATA SYNC/LATCH[x] are Distributed Clocks SyncSignal output or LatchSignal input, depending on SII EEPROM configuration. If an MII port is used, SYNC/LATCH[1]/MI_DATA becomes MI_DATA, which is the Ethernet PHY management interface data signal. SYNC/LATCH signals are not driven (high impedance) until the EEPROM is loaded (MI_DATA is independent of the EEPROM loaded state). NOTE: MI_DATA must have a pull-up resistor (4.7k Ω recommended for ESCs). 3.6 LED Signals All LED signals are also used as configuration signals. The polarity of each LED signal depends on the configuration: LED is active high if pin is pulled down for configuration, and active low if pin is pulled up. Refer to the example schematics for LED connection details. Table 20: LED pins Pin Pin Signal Configuration Internal PU/PD Name Dir Name Dir 18 RUN/EEPROM_SIZE BD RUN O EEPROM_SIZE WPD 16 LINKACT(0)/MODE[0] BD LINKACT(0) O MODE[0] WPD 12 PERR(0)/CLK_MODE[0] BD PERR(0) O CLK_MODE[0] WPD 17 LINKACT(1)/MODE[1] BD LINKACT(1) O MODE[1] WPD 13 PERR(1)/CLK_MODE[1] BD PERR(1) O CLK_MODE[1] WPD RUN/EEPROM_SIZE SII EEPROM_SIZE configuration (either 1 Kbit-16 Kbit or 32 Kbit-4 Mbit) sampled at the beginning of the EEPROM access. Otherwise RUN LED signal, usually. RUN is active high if pin is pulled down, and active low if pin is pulled up. Refer to example schematics for connection details. RUN LED should be green. LINKACT(x)/MODE(x) Chip MODE configuration pin at power-on, Link/Activity LED output (off=no link, on=link without activity, blinking=link and activity) for logical port x afterwards. LINKACT(x) is active high if pin is pulled down, and active low if pin is pulled up. Refer to example schematics for connection details. Link/Activity LED should be green. PERR(x)/CLK_MODE(x) CPU_CLK Mode configuration pin at power-on, Error LED output for logical port x afterwards. PERR(x) is active high if pin is pulled down, and active low if pin is pulled up. Refer to example schematics for connection details. NOTE: PERR(x) LEDs are not part of the EtherCAT indicator specification. They are only intended for testing and debugging. The PERR(x) LED flashes once if a physical layer receive error occurs. Do not confuse PERR(x) LEDs with application layer ERR LED, this is not supported by the ESCs and has to be controlled by a µController. |
