Bit 15: PC Card Memory and IO Modes Supported
This bit, when set, indicates that the PC Card UDMA support values in bits 11-6 are valid. When this bit is
cleared, PC Card Memory and IO Modes are not supported by the device
.
Idle - 97h or E3h
This command causes the CompactFlash Storage Card to set BSY, enter the Idle mode, clear BSY and
generate an interrupt. If the sector count is non-zero, it is interpreted as a timer count with each count being 5
milliseconds and the automatic power down mode is enabled. If the sector count is zero, the automatic power
down mode is disabled. Note that this time base (5 msec) is different from the ATA specification.
