HOST ALL CHANNELS INTERRUPT MASK REGISTER (HAINTMSK)
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.

HOST PORT CONTROL AND STATUS REGISTERS
HOST PORT CONTROL AND STATUS REGISTER (HPRT)
This register is available in both Host and Device modes. 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,
connect status, and test mode for each port. The R_SS_WC bits in this register can trigger an interrupt to the
application through the Host Port Interrupt bit of the Core Interrupt register. On a Port Interrupt, the application
must read this register and clear the bit that caused the interrupt. For the R_SS_WC bits, the application must
write a 1 to the bit to clear the interrupt.
