This bit is cleared when a USB Reset is requested.

Refer to ”DPRAM Management” for more details.

ValueDescription
0

Frees the pipe memory.
1

Allocates the pipe memory.

Bits 3:2 – PBK[1:0]: Pipe Banks

Pipe Banks

This field contains the number of banks for the pipe.

For control pipes, a single-bank pipe (0b00) should be selected.

This field is cleared upon sending a USB reset.

ValueNameDescription
0 1_BANK

Single-bank pipe
1 2_BANK

Double-bank pipe
2 3_BANK

Triple-bank pipe
3

Reserved

Bits 6:4 – PSIZE[2:0]: Pipe Size

Pipe Size

This field contains the size of each pipe bank.

This field is cleared upon sending a USB reset.

ValueNameDescription

Bit 20 – PINGEN: Ping Enable

Ping Enable

This bit is relevant for High-speed Bulk-out transaction only (including the control data stage and the control status stage).

This bit is cleared upon sending a USB reset.

ValueDescription
0

Disables the ping protocol.
1

Enables the ping mechanism according to the USB 2.0 Standard.

Bits 31:24 – BINTERVAL[7:0]: bInterval Parameter for the Bulk-Out/Ping Transaction

bInterval Parameter for the Bulk-Out/Ping Transaction

This field contains the Ping/Bulk-out period.

• If BINTERVAL > 0 and PINGEN = 1, one PING token is sent every bInterval microframe until it is ACKed by the peripheral.

• If BINTERVAL = 0 and PINGEN = 1, multiple consecutive PING tokens are sent in the same microframe until they are ACKed.

• If BINTERVAL > 0 and PINGEN = 0, one OUT token is sent every bInterval microframe until it is ACKed by the peripheral.

• If BINTERVAL = 0 and PINGEN = 0, multiple consecutive OUT tokens are sent in the same microframe until they are ACKed.

This value must be in the range from 0 to 255.
