USB 2.0 PHY (UTMI+)
Maturity plannedTargets ASIC (CMOS) onlyDifficulty HardPriority 1
USB 2.0 HS/FS/LS PHY with 480 MHz PLL, HS current-mode driver, squelch and disconnect detectors, OTG and battery-charging detection and UTMI+ interface.
Planned. This block is specified in the catalog with its interfaces and targets. No implementation exists yet; the skeleton command below generates a lint-clean shell with its ports and registers.
