BITS 0 - 1 DATA RATE SELECT
These bits control the data rate of the floppy
controller. See Table 13 for the settings
corresponding to the individual data rates. The
data rate select bits are unaffected by a
software reset, and are set to 250kb/s after a
hardware reset.
BIT 2 NOPREC
This bit reflects the value of NOPREC bit set in
the CCR register.
BIT 3 DMAEN
This bit reflects the value of DMAEN bit set in
the DOR register bit 3.
BITS 4 - 6 UNDEFINED
Always read as a logic "0"
BIT 7 DSKCHG
This bit monitors the pin of the same name and
reflects the opposite value seen on the pin.
