9.3.10.9 EPx_TX_TYPE_REG Bit Definitions

Table 9-90. EPx_TX_TYPE_REG
Bit NumberNameReset ValueFunction
[7:6]EPx_Speed0Operating speed of the target device:

00: Unused

If selected, the target is assumed to be using the same connection speed as the USB controller.

01: High
10: Full
11: Low
When the core is not configured with the multipoint option, these bits should not be accessed.

[5:4]EPx_Protocol0The Cortex-M3 processor (or fabric master) should set this to select the required protocol for the transmit endpoint:

00: Control
01: ISO
10: Bulk
11: Interrupt

[3:0]EPx_Target Endpoint Number0The Cortex-M3 processor (or fabric master) should set this value to the endpoint number contained in the transmit endpoint descriptor returned to the USB controller during device enumeration.
