System Integration Module (SIM60)
PIV7–PIV0—Periodic Interrupt Vector
6.9.3.7 PERIODIC INTERRUPT TIMER REGISTER (PITR). The PITR contains control for
prescaling the SWT and PIT as well as the count value for the PIT. This register can be read
or written at any time. Bits 15–10 are not implemented and always return zero when read.
A write does not affect these bits.
SWP—Software Watchdog Prescaler Control
PTP—Periodic Timer Prescaler Control
PITR7–PITR0—Periodic Interrupt Timer Register

These bits contain the value of the vector generated during an interrupt acknowledge cy-
cle in response to an interrupt from the PIT. When the SIM60 responds to the interrupt
acknowledge cycle, the periodic interrupt vector from the PICR is placed on the bus. This
vector number is multiplied by 4 to form the vector offset, which is added to the VBR in
the CPU32+ to obtain the address of the vector.
This bit controls the SWT clock source as shown in 6.9.3.5 System Protection Control
Register (SYPCR). The SWP reset value is the inverse of the MODCK1 pin state on the
rising edge of reset.
This bit contains the prescaler control for the PIT. The PTP reset value is the inverse of
the MODCK1 pin state on the rising edge of reset.
These bits contain the remaining bits of the PITR count value for the PIT. A zero value
turns off the PIT. These bits may be written at any time to modify the PIT count value.

0 = SWT clock is not prescaled.
1 = SWT clock is prescaled by a value of 512.
0 = PIT clock is not prescaled.
1 = PIT clock is prescaled by a value of 512.
