0 (OUT): The endpoint direction is OUT.
1 (IN): The endpoint direction is IN (nor for control endpoints).
Bits 6:4 – EPSIZE[2:0] Endpoint Size
This field should be written to select the size of each endpoint bank:
This field is cleared upon receiving a USB reset (except for endpoint 0).
Value Name Description
0
8_BYTE 8 bytes
1
16_BYTE 16 bytes
2
32_BYTE 32 bytes
3
64_BYTE 64 bytes
4

1
2_BANK Double-bank endpoint
2
3_BANK Triple-bank endpoint
3
Reserved
Bit 1 – ALLOC Endpoint Memory Allocate
This bit is cleared upon receiving a USB reset (except for endpoint 0).
Value Description
0
Frees the endpoint memory.
1
Allocates the endpoint memory. The user should check the USBHS_DEVEPTISRx.CFGOK bit to know
whether the allocation of this endpoint is correct.
