8. Sends a PING packet.
This controller is returned to PING packet sending mode by a power-on reset, a software reset,
receiving a NYET/NAK handshake, setting or clearing the sequence toggle bits (SQSET and
SQCLR), and setting the buffer clear bit (ACLRM) in PIPEnCTR.
(2)
Table 23.23 shows the NYET handshake responses of this module. The NYET response of this
module is made in conformance with the conditions noted below. When a short packet is received,
however, the response will be an ACK response instead of a NYET packet response. The same
applies to the data stages of control write transfers.

[Legend]
RCV-BRDY1: When an OUT/PING token is received, there is space in the buffer memory for two or
RCV-BRDY2: When an OUT token is received, there is only enough space in the buffer memory for
RCV-NRDY: When a PING token is received, there is no space in the buffer memory.
TRN-BRDY: When an IN token is received, there is data to be sent in the buffer memory.
TRN-NRDY: When an IN token is received, there is no data to be sent in the buffer memory.
