PATR (Authentication Type in PPPoE mode) [R] [0x001C-0x001D] [0x0000]
This register notifies authentication method that has been agreed at the connection with
PPPoE Server. W5100 supports two types of Authentication method - PAP and CHAP .
PTIMER (PPP Link Control Protocol Request Timer Register) [R/W] [0x0028] [0x28]
This register indicates the duration for sending LCP Echo Request. Value 1 is about 25ms.
Ex) in case that PTIMER is 200,
PMAGIC (PPP Link Control Protocol Magic number Register) [R/W] [0x0029] [0x00]
This register is used in Magic number option during LCP negotiation. Refer to the application
note, “How to connect ADSL”.
UIPR (Unreachable IP Address Register) [R] [0x002A – 0x002D] [0x00]
In case of data transmission using UDP (refer to “5.2.2. UDP”), if transmitting to non-existing
IP address, ICMP (Destination Unreachable) packet will be received. In this case, that IP
address and port number will be saved in the Unreachable IP Address Register(UIPR) and
Unreachable Port Register(UPORT) respectively.
Ex) in case of “192.168.0.11”,
UPORT (Unreachable Port Register) [R] [0x002E – 0x002F] [0x0000]
Refer to Unreachable IP Address Register (UIPR)
Ex) In case of 5000(0x1388),
200 * 25(ms) = 5000(ms) = 5 seconds
