NO.
NAME

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.
14–12
I/O
1
I/O space. The field value (0–7) corresponds to the base number of wait states for I/O space accesses
within addresses 0000–FFFFh. The SWSM bit of the SWCR defines a multiplication factor of 1 or 2 for
the base number of wait states.
11–9
Data
1
Upper data space. The field value (0–7) corresponds to the base number of wait states for external
data space accesses within addresses 8000–FFFFh. The SWSM bit of the SWCR defines a
multiplication factor of 1 or 2 for the base number of wait states.
8–6
Data
1
Lower data space. The field value (0–7) corresponds to the base number of wait states for external
data space accesses within addresses 0000–7FFFh. The SWSM bit of the SWCR defines a
multiplication factor of 1 or 2 for the base number of wait states.
5–3
Program
1
Upper program space. The field value (0–7) 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.
2–0
Program
1
Program space. The field value (0–7) corresponds to the base number of wait states for external
program space accesses within the following addresses:
XPA = 0: x0000–x7FFFh
XPA = 1: 00000–FFFFFh
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 4 and described in
Table 3.

0
These bits are reserved and are unaffected by writes.
0
SWSM
0
Software wait-state multiplier. Used to multiply the number of wait states defined in the SWWSR by a factor
of 1 or 2.
SWSM = 0: wait-state base values are unchanged (multiplied by 1).
SWSM = 1: wait-state base values are multiplied by 2 for a maximum of 14 wait states.
