PHY 0 Register 18: Global Control 2
Table 72. PHY 0 Register 18: Global Control 2
Mode Description
RW
1: If differential service priority is enabled, this bit specifies
differential service code point [A] is high priority
0: If differential service priority is enabled, this bit specifies
differential services code point [A] is low priority
RW
Used to specify the high priority differential service code
point A. For example, if these bits are set to 111111, incoming
packets with a TOS field equal to 111111 will be considered
high priority packets.
RW
1: If differential service priority is enabled, this bit specifies
differential services code point [B] is high priority
0: If differential service priority is enabled, this bit specifies
differential services code point [B] is low priority
RW
Used to specify a high priority differential service code point B.
For example, if these bits are set to 000000, incoming packets
with a TOS field equal to 000000 will be considered high
priority packets.

0: Disable drop packet after SRAM full for 48 pass 1. This will
result in SRAM run out
RW
