Word 164: CF Advanced PCMCIA I/O and Memory Timing Modes Capabilities and Settings
This word describes the capabilities and current settings for CFA defined advanced timing modes using the
Memory and PCMCIA I/O interface.
Notice! The use of PCMCIA I/O or Memory modes that are 100ns or faster impose significant restrictions on the implementation
of the host as indicated in section 4.3.7: Additional Requirements for CF Advanced Timing Modes.

This command causes the device 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
