POLYNOMIAL FRC
CONTROL REGISTER (XR6E)
Read/Write at I/O Address 3B7h/3D7h
Index 6Eh
D7 D6 D5 D4 D3 D2 D1 D0
This register is effective in flat panel mode when
polynomial FRC is enabled (see XR50 bits 0-1). It
is used to control the FRC polynomial counters.
The values in the counters determine the offset in
rows and columns of the FRC count. These values
are usually determined by trial and error.
