153 / 213 page  2010 - 2015 Microchip Technology Inc. DS00001875A-page 153 LAN950x 7.3.27 HS DESCRIPTOR ATTRIBUTES REGISTER (HS_ATTR) This register is supported only by LAN9500A/LAN9500Ai. This register sets the length values for HS descriptors that have been loaded into Descriptor RAM via the Data Port registers. The HS Polling interval is also defined by a field within this register. The Descriptor RAM images may be used, in conjunction with this register, to facilitate customized operation when no EEPROM is present. Note 1: If a descriptor does not exist in Descriptor RAM, its size value must be written as 00h. 2: This register only affects system operation when an EEPROM is not present and the EEPROM Emulation Enable (EEM) bit indicates Descriptor RAM and the Attributes Registers are to be used for descriptor pro- cessing. 3: Writing to this register when an EEPROM is present is prohibited and will result in untoward operation and unexpected results. 4: This register is protected by Reset Protection (RST_PROTECT). Note 7-17 The only legal values are 0 and 0x12h. Writing any other values will result in untoward behavior and unexpected results. Note 7-18 The only legal values are 0 and 0x12h. Writing any other values will result in untoward behavior and unexpected results. Address: 0A0h Size: 32 bits Bits Description Type Default 31:24 RESERVED RO - 23:16 HS Polling Interval (HS_POLL_INT) R/W 04h 15:8 HS Device Descriptor Size (HS_DEV_DESC_SIZE) Note 7-17 R/W 00h 7:0 HS Configuration Descriptor Size (HS_CFG_DESC_SIZE) Note 7-18 R/W 00h |
