A Hi-Speed USB peripheral, host or OTG device handles more than one electrical state as
defined in Universal Serial Bus Specification Rev. 2.0 and On-The-Go Supplement to the
USB 2.0 Specification Rev. 1.3 . The ISP1507 accommodates various states through
register bit settings of XCVRSELECT[1:0], TERMSELECT, OPMODE[1:0],
DP_PULLDOWN and DM_PULLDOWN.

Description
active HIGH transmit enable
transmit differential data on DP and DM when TX_ENABLE is HIGH
receive differential data from DP and DM when TX_ENABLE is LOW
transmit single-ended zero on DP and DM when TX_ENABLE is HIGH
receive single-ended zero from DP and DM when TX_ENABLE is LOW
active HIGH interrupt indication; will be asserted whenever any
unmasked interrupt occurs
reserved; the ISP1507 will drive these pins to LOW
