• Selectable clock for prescaler/glitch filter
• Configurable glitch filter or prescaler
• Interrupt generated on timer compare
• Hardware trigger generated on timer compare
• Four modes of operation
• Extended space operation in time, baseband, and FSK modes
• Selectable input clock divider
• Interrupt on end of cycle
• Ability to disable CMT_IRO signal and use as timer interrupt
• Independent power supply, POR and 32 kHz crystal oscillator
• 32-bit seconds counter with 32-bit alarm
• 16-bit prescaler with compensation
• Register write protection
• Complies with USB specification rev 2.0
• USB host mode
• USB device mode
• Suspend mode/low power
• Includes an on-chip full-speed (12 Mbps) and low-speed (1.5 Mbps) transceiver
• 1 kHz internal LPO
• External low power crystal oscillator
• Internal reference clock (not available in low leakage power modes)
• Secondary external reference clock (for example, 32 kHz crystal)
• Time with independent control of high and low times
• Baseband
• Frequency shift key (FSK)
• Direct software control of CMT_IRO signal
• Hard Lock requires VBAT POR to enable write access
• Soft lock requires system reset to enable write/read access
• Supports enhanced-host-controller interface (EHCI)
• Allows direct connection of FS/LS devices without an OHCI/UHCI companion controller
• Supported by Linux and other commercially available operating systems
• Full-speed operation via the on-chip transceiver
• Supports one upstream facing port
• Supports four programmable, bidirectional USB endpoints, including endpoint 0
• As host, firmware can suspend individual devices or the entire USB and disable chip clocks for low-power
• Device supports low-power suspend
• Remote wake-up supported for host and device
• Integrated with the processor’s low power modes
