17 / 112 page Micrel, Inc. KSZ8864RMN September 2011 17 M9999-092011-1.4 Pin Number Pin Name Type (1) Port Pin Function (2) 50 P2LED0 IPU/O 2 LED indicator for Port 2. Strap option: Switch MAC3 used only. PU (default) = Select MII interface for the Switch MAC3 SW3- MII. PD = Select RMII interface for the Switch MAC3 SW3-RMII. 51 P1LED1 IPU/O 1 LED indicator for Port 1. Strap option: Switch RMII used only. PU (default) = Select the device as clock mode, when use RMII interface, all clock source come from pin x1/x2 crystal 25MHz. PD = Select the device as normal mode when use RMII interface. All clock source comes from SW4-RMII SM4TXC pin with an external input 50MHz clock. In the normal mode, the 25MHz crystal clock from pin X1/X2 doesn’t take affect and should disable SW4-RMII SW4RXC 50MHz clock output by the register 87. The normal mode is used when SW4-RMII receive an external 50MHz RMII reference clock from pin SM4TXC. 52 P1LED0 IPU/O 1 LED indicator for Port 1. Strap option: for Switch MAC4 only. PU (default) = Select MII interface for the Switch MAC4 SW4- MII. PD = Select RMII interface for the Switch MAC4 SW4-RMII. 53 MDC IPU All MII management interface clock. Or SMI interface clock 54 MDIO IPU/O All MII management data I/O. Or SMI interface data I/O Features internal pull down to define pin state when not driven. Note: Need an external pull-up when driven. 55 SPIQ IPU/O All SPI serial data output in SPI slave mode. Note: Need an external pull-up when driven. 56 SPIC/SCL IPU/O All (1) Input clock up to 25MHz in SPI slave mode, (2) output clock at 61KHz in I 2C master mode. Note: Need an external pull-up when driven. 57 SPID/SDA IPU/O All (1) Serial data input in SPI slave mode; (2) serial data input/output in I 2C master mode. Note: Need an external pull-up when driven. 58 SPIS_N IPU All Active low. (1) SPI data transfer start in SPI slave mode. When SPIS_N is high, the device is deselected and SPIQ is held in high impedance state, a high-to-low transition to initiate the SPI data transfer. (2) Not used in I 2C master mode. |
