(detected timeout without detecting a handshake packet from the hub) or an error has been detected in
the hub packet. Here, the controller sets "1" to the bit corresponding to the PIPENRDY bit and modifies
the PID bit of the corresponding pipe to "NAK". When a NRDY interrupt is detected during a C-Split

or S-Split is issued, and when a case occurs continuously three times in any combination where the
Hub does not respond to the In-token issued by the controller (detected timeout without detecting Hub
DATA packet), or an error has been detected in the Hub packet. Here the controller sets "1" to the
PIPENRDY bit corresponding to the pipe and modifies the PID bit of the corresponding pipe to "NAK".
When these conditions occur in a C-Split, the controller clears the CSSTS bit to "0" and sets it.
in any combination where the Hub does not respond to the In-token issued by the controller (a detected
timeout without detecting the DATA packet from the Hub), or an error has been detected in the Hub
packet. In the pipe of Interrupt transfer type, when these conditions occur, the controller sets "1" to the
PIPENRDY bit corresponding to the pipe, modifies the PID bit of the corresponding pipe to "NAK", and
clears the CSSTS bit to "0". In the pipe of isochronous transfer type, when these conditions occur, the
controller sets "1" to the PIPENRDY bit corresponding to the pipe, sets "1" to the CRCE bit, clears the
CSSTS bit to "0" and sets it (the PID bit of the pipe is not modified).
controller sets "1" to the PIPENRDY bit corresponding to the pipe, modifies the PID bit of the

Microframe is "4". The controller sets "1’ in the PIPENRDY bit corresponding to the pipe, sets "1" to the
CRCE bit, clears the CSSTS bit to "0" and sets it (the PID bit of the pipe is not modified).
