PATR (Authentication Type in PPPoE mode) [R] [0xFE001C-0xFE001D] [0x0000]
This register notifies the type of authentication used to establish the PPPoE connection.
PPPALGO (Authentication Algorithm in PPPoE mode)[R][0xFE001E][0x00]
This register notifies the authentication algorithm used for the PPPoE connection. For detail
PTIMER (PPP Link Control Protocol Request Timer Register) [R/W] [0xFE0028] [0x28]
This register indicates the duration of LCP Echo Request being sent. Value 1 is about 25ms.
PMAGIC (PPP Link Control Protocol Magic number Register) [R/W] [0xFE0029][0x00]
This register is used in the Magic number option during LCP negotiation. Refer to the
VERSIONR (W7100A Chip Version Register)[R][0xFE001F][0x02]
This register is W7100A chip version register.
INTLEVEL (Interrupt Low Level Timer Register)[R/W][0xFE0030 – 0xFE0031][0x0000]
The INTLEVEL register sets the Interrupt Assert wait time(I

Ex) in case that PTIMER is 200,
= (2000 + 4000 + 8000 + 16000 + 32000 + ((8 - 4) X 64000)) X 0.1ms
= 318000 X 0.1ms = 31.8s
= (0x07D0 + 0x0FA0 + 0x1F40 + 0x3E80 + 0x7D00 + 0xFA00 + 0xFA00 + 0xFA00 + 0xFA00) X 0.1ms
200 * 25(ms) = 5000(ms) = 5 seconds
