1x/4x LP-Serial Register Block Header
The port maintenance block header 0 register contains the EF_PTR to the next EF_BLK (Extended Features Space,
Error Management) and the EF_ID that identifies this as the generic end point port maintenance block header. Note that
while registers defined by software assisted error recovery are supported, software assisted error recovery is not (these
registers are included for hot insertion only); therefore, RIO is defined here as not supporting software assisted error
recovery. PMBH0CSR is a read-only register.

The above register is described in the RIO Specification Part 6, sec. 6.6.2.1
Port Link Time-out Control CSR
The port link time-out control register contains the time-out timer value for all ports on a device. This time-out is for link
events such as sending a packet to receiving the corresponding acknowledge and sending a link-request to receiving the
corresponding link-response. The reset value is the maximum time-out interval, and represents between 3 and 5 seconds.

Port Response Time-out Control CSR
The port response time-out control register contains the time-out timer count for all ports on a device. This time-out is
for sending a request packet to receiving the corresponding response packet. The reset value is the maximum time-out
interval, and represents between 3 and 5 seconds.
