RM0090 USB on-the-go full-speed (OTG_FS)
OTG_FS Host all channels interrupt mask register (OTG_FS_HAINTMSK)
Address offset: 0x418
Reset value: 0x0000 0000
The host all channel interrupt mask register works with the host all channel interrupt register
to interrupt the application when an event occurs on a channel. There is one interrupt mask
bit per channel, up to a maximum of 16 bits.

OTG_FS Host port control and status register (OTG_FS_HPRT)
Address offset: 0x440
Reset value: 0x0000 0000
This register is available only in host mode. Currently, the OTG host supports only one port.
A single register holds USB port-related information such as USB reset, enable, suspend,
resume, connect status, and test mode for each port. It is shown in Figure 364. The rc_w1
bits in this register can trigger an interrupt to the application through the host port interrupt
bit of the core interrupt register (HPRTINT bit in OTG_FS_GINTSTS). On a Port Interrupt,
the application must read this register and clear the bit that caused the interrupt. For the
rc_w1 bits, the application must write a 1 to the bit to clear the interrupt.
