62 / 85 page  USB333x DS00001880A-page 62 2009 - 2015 Microchip Technology Inc. 7.1.1.9 USB Interrupt Enable Falling Address = 10-12h (read), 10h (write), 11h (set), 12h (clear) 7.1.1.10 USB Interrupt Status Address = 13h (read only) This register dynamically updates to reflect current status of interrupt sources. Note: The default value is only valid after POR. When the register is read it will match the current status of the comparators at the moment the register is read. Field Name Bit Access Default Description HostDisconnect Fall 0 rd/w/s/c 1b Generate an interrupt event notification when Hostdisconnect changes from high to low. Applicable only in host mode. VbusValid Fall 1 rd/w/s/c 1b Generate an interrupt event notification when Vbusvalid changes from high to low. SessValid Fall 2 rd/w/s/c 1b Generate an interrupt event notification when SessValid changes from high to low. SessEnd Fall 3 rd/w/s/c 1b Generate an interrupt event notification when SessEnd changes from high to low. IdGnd Fall 4 rd/w/s/c 1b Generate an interrupt event notification when IdGnd changes from high to low. Reserved 7:5 rd 0h Read only, 0. Field Name Bit Access Default Description HostDisconnect 0 rd (read only) 0b Current value of the UTMI+ HS Hostdisconnect output. Applicable only in host mode. VbusValid 1 0b Current value of the UTMI+ Vbusvalid output. If VbusValid Rise and VbusValid Fall are set this register will read 0. SessValid 2 0b Current value of the UTMI+ SessValid output. This register will always read the current status of the Session Valid comparator regardless of the SessValid Rise and SessValid Fall settings. SessEnd 3 0b Current value of the UTMI+ SessEnd output. If SessEnd Rise and SessEnd Fall are set this register will read 0. IdGnd 4 0b Current value of the UTMI+ IdGnd output. Reserved 7:5 0h Read only, 0. |
