The SIPRR register bits are described in Table 4-5.
4.3.1.3 CPM Interrupt Priority Registers (SCPRR_H and SCPRR_L)
The CPM high interrupt priority register (SCPRR_H), shown in Figure 4-12, deÞne
priorities between the FCCs and MCCs.

Name
Description
0Ð3
XS1PÐXSIU1
Priority order. DeÞnes which PIT/TMCNT/IRQs asserts its request in the XSIU1 priority
position. The user should not program the same PIT/TMCNT/IRQs to more than one priority
position (1Ð8). These bits can be changed dynamically.
000 TMCNT asserts its request in the XSIU1 position.
001 PIT asserts its request in the XSIU1 position.
010 Reserved
011 IRQ1 asserts its request in the XSIU1 position.
100 IRQ2 asserts its request in the XSIU1 position.
101 IRQ3 asserts its request in the XSIU1 position.
110 IRQ4 asserts its request in the XSIU1 position.
111 IRQ5 asserts its request in the XSIU1 position.
4Ð12
XS2PÐ XS8P
Same as XS1P, but for XSIU2ÐXSIU8.
13Ð15
Ñ
Reserved, should be cleared.
