PRELIMINARY
Publication Release Date: Nov. 2000
- 106 - Revision 0.60
CR26 (Default 0b0s000000)
Bit 7
: SEL4FDD
= 0 Select two FDD mode.
= 1 Select four FDD mode.
Bit 6
: HEFRAS
This bit defines how to enable Configuration mode. The corresponding power-on setting pin
is NRTSA (pin 51).
= 0 Write 87h to the location 2Eh twice.
= 1 Write 87h to the location 4Eh twice.
Bit 5
: LOCKREG
= 0 Enable R/W Configuration Registers.
= 1 Disable R/W Configuration Registers.
Bit 4
:Reserve
Bit 3
: DSFDLGRQ
= 0 Enable FDC legacy mode on IRQ and DRQ selection, then DO register bit 3 is
effective on selecting IRQ.
= 1
Disable FDC legacy mode on IRQ and DRQ selection, then DO register bit 3 is not
effective on selecting IRQ.
Bit 2
: DSPRLGRQ
= 0
Enable PRT legacy mode on IRQ and DRQ selection, then DCR bit 4 is effective on
selecting IRQ.
= 1
Disable PRT legacy mode on IRQ and DRQ selection, then DCR bit 4 is not effective
on selecting IRQ.
Bit 1
: DSUALGRQ
= 0
Enable UART A legacy mode IRQ selecting, then MCR bit 3 is effective on selecting
IRQ.
= 1 Disable UART A legacy mode IRQ selecting, then MCR bit 3 is not effective on
selecting IRQ.
Bit 0
: DSUBLGRQ
= 0
Enable UART B legacy mode IRQ selecting, then MCR bit 3 is effective on selecting
IRQ.
= 1 Disable UART B legacy mode IRQ selecting, then MCR bit 3 is not effective on
selecting IRQ.
