Access Types
Table 20-1.
1)
uration section at the end of this chapter.
2)
Each configuration register can be accessed in four different ways. The first address location
can be used to write the register directly. This address can also be used to read the register
value. The following addresses facilitate three different types of write access to the register. Per-
forming a “set” access, all bits written to one will be set. Bits written to zero will be unchanged by
the operation. Performing a “clear” access, all bits written to one will be cleared. Bits written to
zero will be unchanged by the operation. Finally, a toggle access will toggle the value of all bits
written to one. Again all bits written to zero remain unchanged. Note that for some registers (e.g.
IFR), not all access methods are permitted.
Note that for ports with less than 32 bits, the corresponding control registers will have unused
bits. This is also the case for features that are not implemented for a specific pin. Writing to an
unused bit will have no effect. Reading unused bits will always return 0.

The reset value for these registers are device specific. Please refer to the Module Config-
The reset value is undefined depending on the pin states.
