12 / 233 page  KSZ9567R DS00002329E-page 12 2022 Microchip Technology Inc. and its subsidiaries Port 7-6 Collision Detect COL[7:6] IPD/O8 MII Mode: Port 7-6 Collision Detect. In PHY mode this pin is an output, in MAC mode it is an input. RMII/RGMII Modes: Not used. Do not connect this pin in these modes of operation. Port 7-6 Transmit Data 3 TXD[7:6]_3 IPD MII/RGMII Modes: Port 7-6 Transmit Data bus bit 3. RMII Mode: Not used. Do not connect this pin in this mode of operation. Port 7-6 Transmit Data 2 TXD[7:6]_2 IPD MII/RGMII Modes: Port 7-6 Transmit Data bus bit 2. RMII Mode: Not used. Do not connect this pin in this mode of operation. Port 7-6 Transmit Data 1 TXD[7:6]_1 IPD MII/RMII/RGMII Modes: Port 7-6 Transmit Data bus bit 1. Port 7-6 Transmit Data 0 TXD[7:6]_0 IPD MII/RMII/RGMII Modes: Port 7-6 Transmit Data bus bit 0. Port 7-6 Receive/ Reference Clock RX_CLK[7:6]/ REFCLKO[7:6] I/O24 MII Mode: RX_CLK[7:6] is the Port 7-6 25/2.5MHz Receive Clock. In PHY mode this pin is an output, in MAC mode it is an input. RMII Mode: REFCLKO[7:6] is the Port 7-6 50MHz Refer- ence Clock output when in RMII Clock mode. This pin is unused when in RMII Normal mode. RGMII Mode: RX_CLK[7:6] is the Port 7-6 125/25/2.5MHz Receive Clock output. Port 7-6 Receive Data Valid / Carrier Sense / Control RX_DV[7:6]/ CRS_DV[7:6]/ RX_CTL[7:6] IPD/O24 MII Mode: RX_DV[7:6] is the Port 7-6 Received Data Valid output. RMII Mode: CRS_DV[7:6] is the Carrier Sense / Receive Data Valid output. RGMII Mode: RX_CTL[7:6] is the Receive Control output. Note: The RX_DV7/CRS_DV7/RX_CTL7 pin also pro- vides configuration strap functions during hard- ware/software resets. Refer to Section 3.2.1, "Configuration Straps" for additional information. Port 7-6 Receive Error RX_ER[7:6] IPD/O24 MII/RMII Modes: Port 7-6 Receive Error output. RGMII Modes: Not used. Do not connect this pin in this mode of operation. Port 7-6 Carrier Sense CRS[7:6] IPD/O8 MII Mode: Port 7-6 Carrier Sense. In PHY mode this pin is an output, in MAC mode it is an input. RMII/RGMII Modes: Not used. Do not connect this pin in these modes of operation. TABLE 3-2: PIN DESCRIPTIONS (CONTINUED) NAME SYMBOL BUFFER TYPE DESCRIPTION |
