62 / 125 page ![]() LAN91C111 DS00002276A-page 62 2011-2016 Microchip Technology Inc. 8.23 Bank 3 - Management Interface MSK_CRS100 - Disables CRS100 detection during transmit in half duplex mode (SWFDUP=0). MDO - MII Management output. The value of this bit drives the MDO pin. MDI - MII Management input. The value of the MDI pin is readable using this bit. MDCLK - MII Management clock. The value of this bit drives the MDCLK pin. MDOE - MII Management output enable. When high pin MDO is driven, when low pin MDO is tri-stated. The purpose of this interface, along with the corresponding pins is to implement MII PHY management in software. 8.24 Bank 3 - Revision Register CHIP - Chip ID. Can be used by software drivers to identify the device used. REV - Revision ID. Incremented for each revision of a given device.
