CY7C67300
Done1 Flag (Bit 2)
In host mode the Done 1 Flag bit is a read only bit that indicates
if a host packet done interrupt occurs on Host 1. In device mode
this read only bit indicates if an any of the endpoint interrupts
occur on Device 1. Firmware needs to determine which endpoint
interrupt occurred.
1: Interrupt triggered
0: Interrupt did not trigger
Reset1 Flag (Bit 1)
The Reset1 Flag bit is a read only bit that indicates if a USB
Reset interrupt occurs on either Host/Device 1.
1: Interrupt triggered
0: Interrupt did not trigger
Mailbox Out Flag (Bit 0)
The Mailbox Out Flag bit is a read only bit that indicates if a
message is ready in the outgoing mailbox. This interrupt clears
when the external host reads from the HPI Mailbox register.
1: Interrupt triggered
0: Interrupt did not trigger
SPI Registers
There are twelve registers dedicated to SPI operation. Each of these registers is covered in this section and summarized in Table 104.
