ACTIVE
Interrupt active flags:
0 = interrupt not active
1 = interrupt active.
A bit reads as one if the status of the corresponding interrupt is active or active and pending.
4.2.7 Interrupt Priority Registers
The IPR0-IPRm registers provide an 3-bit priority field for each interrupt. These registers are byte-
accessible. See the register summary in Table 4.2 (p. 88) for their attributes. Each register holds
four priority fields, that map to four elements in the CMSIS interrupt priority array IP[0] to IP[n-1],
as shown:
IP[ n-1]

Priority, byte offset 0
Each priority field holds a priority value, 0-7. The lower the value, the greater the
priority of the corresponding interrupt. Only bits[7:5] of each field are implemented,
bits[4:0] read as zero and ignore writes.
See Section 4.2.1 (p. 89) for more information about the IP[0] to IP[n-1] interrupt priority array,
that provides the software view of the interrupt priorities.
Find the IPR number and byte offset for interrupt N (n, the maximum number for N is given by Table 1.1 (p.
5) and subtracted by 1) as follows:
the corresponding IPR number, k, is given by k = N DIV 4
the byte offset of the required Priority field in this register is N MOD 4, where:
byte offset 0 refers to register bits[7:0]
byte offset 1 refers to register bits[15:8]
