0xE0033500
10.16.11 PROT_EPI_CS1
SuperSpeed IN Endpoint Control and Status Register
There are 16 PROT_EPI_CS1 registers. The address of each is calculated as PROT_EPI_CS1(x) = 0xE0033500 + (x*0x4).
Hence PROT_EPI_CS1(0) is at address 0xE0033500, PROT_EPI_CS1(1) is at address 0xE0033500 + 0x4 and so on. The
definition of each of these is the same.
Endpoint IN Control and Status:
â– Setup USB Package buffering, ISO/BULK/INT, IN/OUT and enable/disable endpoint
â– Power up default the payload is 64-byte (Max payload count for Full Speed). In High Speed the payload can be up to 512
for BULK and 1024 for ISO
29 FIRST_ACK_NUMP_0_MASK Interrupt mask for FIRST_ACK_NUMP_0 bit
28 STREAM_ERROR_MASK Interrupt mask for STREAM_ERROR bit
27 DBTERM_MASK Interrupt mask for DBTERM bit
26 HBTERM_MASK Interrupt mask for HBTERM bit
25 OOSERR_MASK Interrupt mask for OOSERR bit
