FX3 P-Port Register Access
10.2.4 PP_INTR_MASK Register
P-port Interrupt Mask register. This register has the same layout as PP_EVENT register and mask
which event lead to assertion of INTR.
10.2.5 PP_DRQR5_MASK
P-Port DRQ/R5 Mask Register. This register has the same layout as PP_EVENT and mask which
events lead to assertion of INTR or DRQ/R5 respectively. DRQR5 is a signal that can be put on any
GPIF CTRL[x] line (see GPIF_BUS_SELECT).
10.2.6 PP_SOCK_MASK
P-Port Socket Mask Register. This registers contain a mask that indicates which sockets affect the
SOCK_AGG_A and SOCK_AGG_B values respectively.
