Reg 64H, Reg 65H, and Reg 66H will load the number of cells transmitted from an internal counter approximately 200 ns
after a write operation is done to Reg 64H, Reg 65H, Reg 66H, or Reg 00H. At that time (200 ns after the write operation),
this register is updated and the internal transmit cell counter is reset to zero or one (depending on whether a cell transmission
has occurred while the write occurs) to begin another round of accumulation. Reading Reg 64H, Reg 65H, and Reg 66H after
the write yields the number of cells transmitted since the counter was last reset, if overflow has not occurred. TCELL[18:0]
should be polled once a second to prevent the register from being saturated.
