Bits 13:12 – NBUSYBK[1:0] Number of Busy Banks
This field indicates the number of busy banks.
For an OUT pipe, this field indicates the number of busy banks, filled by the user
, ready for an OUT transfer. When all
banks are busy, this triggers a PEP_x interrupt if USBHS_HSTPIPIMRx.NBUSYBKE = 1.
For an IN pipe, this field indicates the number of busy banks filled by IN transaction from the device. When all banks
are free, this triggers a PEP_x interrupt if USBHS_HSTPIPIMRx.NBUSYBKE = 1.
Value Name Description
0
0_BUSY 0 busy bank (all banks free)
1
1_BUSY 1 busy bank
2
2_BUSY 2 busy banks
3
3_BUSY 3 busy banks
Bits 9:8 – DTSEQ[1:0] Data T
oggle Sequence
This field indicates the data PID of the current bank.
For an OUT pipe, this field indicates the data toggle of the next packet that is to be sent.
For an IN pipe, this field indicates the data toggle of the received packet stored in the current bank.
Value Name Description
0
DATA0 Data0 toggle sequence
1
DATA1 Data1 toggle sequence

Bit 7 – SHORTPACKETI Short Packet Interrupt
Value Description
0
Cleared when USBHS_HSTPIPICR.SHORTPACKETIC = 1.
1
Set when a short packet is received by the host controller (packet length inferior to the PSIZE
programmed field).
Bit 6 – RXSTALLDI Received ST
ALLed Interrupt
Value Description
0
Cleared when USBHS_HSTPIPICR.RXSTALLDIC = 1.
1
Set when a STALL handshake has been received on the current bank of the pipe. The pipe is
automatically frozen. This triggers an interrupt if USBHS_HSTPIPIMR.RXST
ALLE = 1.
Bit 5 – OVERFI Overflow Interrupt
Value Description
0
Cleared when USBHS_HSTPIPICR.OVERFIC = 1.
1
Set when the current pipe has received more data than the maximum length of the current pipe. An
interrupt is triggered if the USBHS_HSTPIPIMR.OVERFIE bit = 1.
Bit 4 – NAKEDI NAKed Interrupt
Value Description
0
Cleared when USBHS_HSTPIPICR.NAKEDIC = 1.
1
Set when a NAK has been received on the current bank of the pipe. This triggers an interrupt if the
USBHS_HSTPIPIMR.NAKEDE bit = 1.
Bit 3 – PERRI Pipe Error Interrupt
Value Description
0
Cleared when the error source bit is cleared.
