management and control (the configuration registers) are located. Note that the CIS section is a
ROM area in which only read access is possible, and which cannot be written to by the host.
Next, it is necessary to specify the location of control-related registers and make the appropriate
settings, based on information from the CIS section. These control-related registers are called the
configuration registers.
The CIS section and configuration registers are both in an area called the card attribute region. The
write access sequence for this region is shown in table 3.1, and detailed timing specifications are
given in tables 3.2 and 3.3.
Write-related information applies only to accesses to the configuration registers, since the CIS
section is a read-only area.
As shown in table 3.1, the attribute region is allocated to the even byte (D0–D7) parts of even
addresses in the card., and consists entirely of 8-bit registers. Odd byte (D8–D15) parts are invalid
data. Mapping of the task file region described later is also performed by these registers.
Note:
The configuration registers are used to set the operating mode of the card. It might
therefore be supposed that switching between PC-ATA specifications and True-IDE
specifications in a flash card can also be performed by means of these registers, but this is
not the case. These registers can only be used with the PC-ATA specifications. Whether a
flash card is set to the PC-ATA specifications or True-IDE specifications depends on the
input pin settings when the power is turned on; once the card has been started up in a
particular mode, the mode can only be changed by turning on the power again.
