31.10.4 APC Data Structure
The APC data structure consists of three elements: the APC parameter tables for the PHY
devices, the APC priority table, and the APC scheduling tables. See Figure 31-38.

Freescale Semiconductor, Inc.
Enables FMC transmission. Initialize to 1.
FMC time stamp enable
0 The time stamp field of the FMC is coded with all 1's.
1 The value of the time stamp timer is inserted into the time stamp field of the FMC.
Reserved, should be cleared.
Performance monitoring block size ranging from 1 to 2,047 cells.
Reserved, should be cleared.
TX cell count. Used by the CP to count data cells sent. Initialize to zero.
Total user cell 1. Count of CLP = 1 user cells (modulo 65,536) sent. Should be cleared
initially.
Total user cell 0. Count of CLP = 0 user cells (modulo 65,536) sent. Should be cleared
initially.
block of user cells sent since the last FMC. Should be cleared initially.
