Name
This register consists of a 16-bit address pointer that points to the beginning of the
VPI Index table, and a 16-bit address pointer that points to the beginning of the
RSM VCC table. Since both tables reside in SAR-shared memory, the tables start
on 128-byte boundaries. The size of the VPI Index table used in the direct index
method is dependent upon the setting of RSM_CTRL0(VPI_MASK).
This register sets the base address in SRC local memory for the ER_SHIFT tables
used in implicit host congestion ER reduction. The base addresses are 128-byte
aligned, and only the 16 most significant bits of the address are specified in the
ERS_BASE register.

Reassembly Time-out Interrupt Period. The value in this register determines
the number of SYSCLK periods for each time-out interrupt. A value of 0
divides by 65,538.
Reassembly Time-out Counter. The value in this register plus one determines
the number of time-out interrupts that occur in each pass through the RSM
VCC table.
