RESET:
This field specifies the periodic interrupt vector number supplied by the SIM when the
CPU16 acknowledges an interrupt request.
Contains the count value for the periodic timer. This register can be read or written at
any time.
This field determines the periodic interrupt rate. Use the following equations to calcu-
late timer period.
The following equation calculates the PIT period when a slow reference frequency is
used:
The following equation calculates the PIT period when a fast reference frequency is
used:
The following equation calculates the PIT period for an externally input clock frequen-
cy on both slow and fast reference frequency devices.
0 = Periodic timer clock not prescaled.
1 = Periodic timer clock prescaled by a value of 512.
