Alternate Status Register
(Address 1F7h[177h]/3F6h[376h];Offset 7/ Eh)
These registers return the CompactFlash Storage Card status when read by the host. Reading
the Status register does clear a pending interrupt, while reading the Alternate Status register does not. The status
bits are described as follows:

Status & Alternate Status Register
Bit 7 (BUSY
): the busy bit is set when the CompactFlash Storage Card has access to the
command buffer and registers and the host is locked out from accessing the command
register and buffer. No other bits in this register are valid when this bit is set to a 1.
Bit 6 (DRDY
): DRDY indicates whether the device is capable of performing CompactFlash Storage Card
operations. This bit is cleared at power up and remains cleared until the CompactFlash Storage Card is ready to
