VALUE
FUNCTION

XPA
0
Extended program address control bit. XPA is used in conjunction with the program space fields
(bits 0 through 5) to select the address range for program space wait states.
1412
I/O
1
I/O space. The field value (07) corresponds to the base number of wait states for I/O space accesses
within addresses 0000FFFFh. The SWSM bit of the SWCR defines a multiplication factor of 1 or 2 for
the base number of wait states.
119
Data
1
Upper data space. The field value (07) corresponds to the base number of wait states for external
data space accesses within addresses 8000FFFFh. The SWSM bit of the SWCR defines a
multiplication factor of 1 or 2 for the base number of wait states.
86
Data
1
Lower data space. The field value (07) corresponds to the base number of wait states for external
data space accesses within addresses 00007FFFh. The SWSM bit of the SWCR defines a
multiplication factor of 1 or 2 for the base number of wait states.
53
Program
1
Upper program space. The field value (07) corresponds to the base number of wait states for external
program space accesses within the following addresses:
- XPA = 0: x8000 xFFFFh
- XPA = 1: The upper program space bit field has no effect on wait states.
The SWSM bit of the SWCR defines a multiplication factor of 1 or 2 for the base number of wait states.

Program
1
Program space. The field value (07) corresponds to the base number of wait states for external
program space accesses within the following addresses:
- XPA = 0: x0000x7FFFh
- XPA = 1: 00000FFFFFh
The SWSM bit of the SWCR defines a multiplication factor of 1 or 2 for the base number of wait states.
The software wait-state multiplier bit of the software wait-state configuration register is used to extend the base
number of wait states selected by the SWWSR. The SWCR bit fields are shown in Figure 33 and described
in Table 32.
