136 / 226 page ![]() KSZ9563R DS00002419D-page 136 2017-2018 Microchip Technology Inc. Note 5-4 The default value of this field is determined by the associated configuration strap value. Refer to Section 3.2.1, "Configuration Straps," on page 16 for additional information. 11 Power Down 1 = Power-down mode 0 = Normal operation When this bit is set to ‘1’, the link-down status might not get updated in the PHY status register. Software should note link is down and should not rely on the PHY status register link status. After this bit is changed from ‘1’ to ‘0’, an internal reset is performed. Wait a minimum of 1ms before read/write access to this PHY’s registers. R/W 0b 10 Isolate 1 = Logical isolation of the PHY from the switch core 0 = Normal operation R/W 0b 9 Re-start Auto-Negotiation Set this bit to re-start auto-negotiation. This bit is self-clearing. R/W, SC 0b 8 Duplex Mode This bit is ignored if auto-negotiation is enabled (bit 12 in this register). 1 = Full duplex 0 = Half duplex R/W 1b 7 Collision Test 1 = Enable COL test 0 = Disable COL test R/W 0b 6 Speed Select (MSB) This bit is ignored if auto-negotiation is enabled (bit 12 in this register). Bits [6, 13] 11 = Reserved 10 = 1000 Mb/s 01 = 100 Mb/s 00 = 10 Mb/s R/W Note 5-4 5:0 RESERVED RO 0x00 Bits Description Type Default |
