43.15.24 OTG Host all channels interrupt register (OTG_HAINT)
Address offset: 0x414
Reset value: 0x0000 000
When a significant event occurs on a channel, the host all channels interrupt register
interrupts the application using the host channels interrupt bit of the Core interrupt register
(HCINT bit in OTG_GINTSTS). This is shown in Figure 501. There is one interrupt bit per
channel, up to a maximum of 16 bits. Bits in this register are set and cleared when the
application sets and clears bits in the corresponding host channel-x interrupt register.
43.15.25 OTG Host all channels interrupt mask register
(OTG_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.
