x_PICB—Position in Current Buffer Register
(Modem—D31:F6)
I/O Address:
Default Value:
Lockable:
Software can read the registers at the offsets 08h, 0Ah, and 0Bh by performing a 32-bit read from
the address offset 08h. Software can also read this register individually by doing a single, 16-bit
read to offset 08h. Reads across DWord boundaries are not supported.
x_PIV—Prefetch Index Value Register
(Modem—D31:F6)
I/O Address:
Default Value:
Lockable:
Software can read the registers at the offsets 08h, 0Ah, and 0Bh by performing a 32-bit read from
the address offset 08h. Software can also read this register individually by doing a single, 8-bit read
to offset 0Ah. Reads across DWord boundaries are not supported.
