6 / 18 page 6/18 MTD655 Revision 2.0 17/03/2000 MTD655 MYSON TECHNOLOGY ICLK10 83 I/O 10M Inter-Bus port clock. IDAT10 81 I/O 10M Inter-Bus port data bit 100M Inter-Bus Interface pins Name Pin Number I/O Descriptions IACKB100 75 I/O 100M Inter-Bus port access acknowledge signal (low active). For master hub, this pin is output; for slave hub is input, or while EXT_ARB jumper was set to “1”, this pin is input from an external arbitration device. ICOLB100 76 I/O 100M Inter-Bus collision signal (low active). For master hub, this pin can output multi hub collision event to inform all slave hub ; for slave hub, this pin is an input, or while EXT_ARB jumper was set to “1”, this pin is input from an external arbitration device. IREQ100_IN0 79 I 100M Inter-Bus port access request input. IREQ100_IN1 78 I 100M Inter-Bus port access request input. IREQ100_IN2 77 I 100M Inter-Bus port access request input. IREQ100_OUT 80 O 100M Inter-Bus port access request output. ICLK100 73 I/O 100M Inter-Bus port clock. IDAT100_0 71 I/O 100M Inter-Bus port data bit 0. IDAT100_1 70 I/O 100M Inter-Bus port data bit 1. IDAT100_2 69 I/O 100M Inter-Bus port data bit 2. IDAT100_3 68 I/O 100M Inter-Bus port data bit 3. LED Interface Pins Name Pin Number I/O Descriptions LEDDAT 124 I/O LED display serial data out; mapping for LEDCLK signal’s burst clock , its serial out data sequence is : ( first bit be shifted out is from b00, and end of burst bit is b23) b00: *********** b08: 10hub_col b16: ************ b01: ********** b09: 100hub_col b17: ************ b02: ********** b10: asram_test_fail b18: ************ b03: port0 partition b11: port0 partition b19: port0 rx_activity b04: port1 partition b12: port1 partition b20: port1 rx_activity b05: port2 partition b13: port2 partition b21: port2 rx_activity b06: port3 partition b14: port3 partition b22: port3 rx_activity b07: port4 partition b15: port4 partition b23: port4 rx_activity LEDCLK 125 I/O LED display clock signal, the signal is a discontinued clock for LED data serial shift out. Every clock burst have 24 cycles ( period : 160 ns), and the clock burst will be repeated with every 42ms. 10M Inter-Bus Interface pins Name Pin Number I/O Descriptions |
