Table 17-23 describes the fields of the PLTOCCSR.

17.3.1.18 Port Response Time-Out Control Command and Status Register

(PRTOCCSR)

PRTOCCSR, shown in Figure 17-20, contains the time-out timer value used to monitor port

events, for instance, between sending a request packet and receiving the corresponding response

packet.

Table 17-24 describes the fields of the PRTOCCSR.
