PD6710/’22 — ISA-to-PC-Card (PCMCIA) Controllers
Bit Naming Conventions
The following keywords are used within bit and field names:
Keyword
Description
Indicates that the function described in the
rest of the bit name is active when the bit is ‘1’.
Enable
Disable
Mode
Indicates that the function described in the
rest of the bit name is active when the bit is ‘0’.
Indicates that the function of the bit alters the
interpretation of the values in other registers.
Input
Indicates a bit or field that is read from a pin.
Indicates a bit or field that is driven to a pin.
Output
Indicates that the bit or field selects between
multiple alternatives. Fields that contain
Select in their names have an indirect
mapping between the value of the field and
the effect.
Select
Indicates one of two types of bits: either read-
only bits used by the PD67XX to report
information to the system, or bits set by the
PD67XX in response to an event, and can
also be cleared by the system. The system
cannot directly cause a Status bit to become
‘1’.
Status
Value
Indicates that the bit or field value is used as a
number.
Read/Write Convention
Bit Access
Description
Bit is read/write and resets to value n when
PWRGOOD is cycled.
RW:n
Bit is read-only and setting is determined by
conditions noted. Set this bit to ‘0’, or echo
back value read.
R
Bit is read-only and resets to value n when
PWRGOOD is cycled. Set this bit to ‘0’, or
echo back value read.
R:n
Bit is read/write and resets to value n when
PWRGOOD is cycled. Set this bit to value m
only.
R:n W:m
