4.3.2.6 PERIODIC INTERRUPT CONTROL REGISTER (PICR). The PICR contains the
interrupt level and the vector number for the periodic interrupt request. This register can
be read or written at any time. Bits 15–11 are unimplemented and always return zero; a
write to these bits has no effect.

These bits contain the periodic interrupt request level. Table 4-9 lists which interrupt
request level is asserted during an IACK cycle when a periodic interrupt is generated.
The periodic timer continues to run when the interrupt is disabled.

Use caution with a level 7 interrupt encoding due to the
SIM40's interrupt servicing order. See 4.2.2.7 Simultaneous
Interrupts by Sources in the SIM40 for the servicing order.
