Contains information concerning periodic interrupt priority and vectoring. PICR[10:0]
can be read or written at any time. PICR[15:11] are unimplemented and always return
zero.
This field determines the priority of periodic interrupt requests.
The bits of this field contain the interrupt vector number supplied by the SIM when the
CPU acknowledges an interrupt request.
Contains the count value for the periodic timer. This register can be read or written at
any time.
This is the 8-bit timing modulus used to determine periodic interrupt rate. Use the fol-
lowing expression to calculate timer period.
When the software watchdog is enabled, a service sequence must be written to this
register within a specific interval. When read, SWSR always returns $00. Register
shown with read value.
Register is used for factory test only.
Register is used for factory test only.
