With SPMEVFILTR<n>_EL0 and SPMEVFILT2R<n>_EL0, configures when event counter SPMEVCNTR<n>_EL0 in System PMU <s> increments.
The contents of this register are IMPLEMENTATION DEFINED. An Event Type Select Register typically contains:
This register is present only when FEAT_SPMU is implemented. Otherwise, direct accesses to SPMEVTYPER<n>_EL0 are UNDEFINED.
SPMEVTYPER<n>_EL0 is a 64-bit register.

The reset behavior of this field is:
To access SPMEVTYPER<n>_EL0 for System PMU <s>, set SPMSELR_EL0.SYSPMUSEL to s and SPMSELR_EL0.BANK to n[5:4].
SPMEVTYPER<n>_EL0 reads-as-zero and ignores writes if any of the following are true:
