Hexadecimal values are expressed as in the following example. (This value is expressed as 42 in
the decimal system.)
KB (kilobyte) = 1,024 Bytes,
MB (megabyte) = 1,024 × 1,024 = 1,048,576 Bytes,
GB (gigabyte) = 1,024 × 1,024 × 1,024 = 1,073,741,824 Bytes
Byte: 8 bits
Half-word: 2 consecutive Bytes (16 bits)
Word: 4 consecutive Bytes (32 bits)
Double-word: 8 consecutive Bytes (64 bits)
An asterisk (“*”) is added to the end of signal names to indicate Low Active signals. (Example:
RESET*)
“Assert” means to move a signal to its Active level. “Deassert” means to move a signal to its
Inactive level.
Bit operation is expressed as follows.
Set: Put a bit in the “1” position.
Clear: Put a bit in the “0” position.
Properties of each bit in a register are expressed as follows.
R:
W:
R/W:
W1C
R/W1C: Read/Write 1 Clear. These bits can be read from and written to. The corresponding bit is
R/W0C: Read/Write 0 Clear. These bits can be read from and written to. The corresponding bit is
R/W1S Read/Write 1 Set. These bits can be read from and written to. The corresponding bit is set
RS/WC Read Set/Write Clear. These bits can be read from and written to. The bits is set
R/L:
Registers and the register bit/field name are expressed as “<register name>.<bit/field name>”.
The above example indicates Time Out Bus Error Enable (TOE), a bit field of bit 14 in the Chip
Configuration Register (CCFG).
Example: CCFG.TOE
Read only. The software cannot change the bit value.
Write only. The value that is read is undefined.
Read/Write is possible.
Write 1 Clear. This corresponding bit is cleared when “1” is written to this bit. “0” is
invalid if written.
cleared when “1” is written to this bit. “0” is invalid if written.
cleared when “0” is written to this bit. “1” is invalid if written.
when “1” is written to this bit. “0” is invalid if written.
when read, and a write of an arbitrary value to the bit clears it.
Property unique to the PCI Controller. This bit can be read. The value of this bit can only
be changed by the method described in “10.3.14: Set Configuration Space”.
