NOTE
To prevent bus conflicts, when using internal read visibility, the user must
disable all external devices from driving the data bus during any internal
access.
PSEL3–PSEL0 — Priority Selects
These four bits are used to specify one I bit related interrupt source, which then becomes the highest
priority I bit related interrupt source. These bits may be written only while the I bit in the CCR is set,
inhibiting I bit related interrupts. An interpretation of the value of these bits is shown in Table 4-4.
During reset, PSEL3–PSEL0 are initialized to 0101, which corresponds to reserved (default to IRQ).
IRQ becomes the highest priority I bit related interrupt source.
