10.11.6 DEV_EPI_CS
IN Endpoint Control and Status Register
There are 16 DEV_EPI_CS registers corresponding to each of the possible IN endpoints. The address of each is calculated
as DEV_EPI_CS(x) = 0xE0031418 + (x*0x4). Hence DEV_EPI_CS(0) is at address 0xE0031418, DEV_EPI_CS(1) is at
address 0xE0031418 + 0x4 and so on. The definition of each of these is the same.
Endpoint IN Control and Status:
■ Set up USB Package buffering, ISO/BULK/INT, IN/OUT and enable/disable endpoint
■ 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.
31 ISOERR_MASK Interrupt mask for ISOERR bit
30 SHORT_MASK Interrupt mask for SHORT bit
29 ZERO_MASK Interrupt mask for ZERO bit
28 DONE_MASK Interrupt mask for DONE bit
27 BNAK_MASK Interrupt mask for BNAK bit
26 COMMIT_MASK Interrupt mask for COMMIT bit
