System Configuration and Protection
6.2.2.4.7
The RTCAL is a 32-bit read/write register. When the value of the RTC is equal to the value programmed
in the alarm register, a maskable interrupt is generated.
The alarm interrupt will be generated as soon as there is a match between the ALARM field and the
corresponding bits in the RTC. The resolution of the alarm is 1 second. This register is locked after reset
by default. Unlocking is accomplished by writing 0x55CC AA33 to its associated key register. See
Section 8.8.3.2, “Keep-Alive Power Registers Lock
6.2.2.4.8
The PISCR contains the interrupt request level and the interrupt status bit. It also contains the controls for
the 16-bits to be loaded into a modulus counter. This register can be read or written at any time.

Periodic interrupt request. These bits determine the interrupt priority level of the PIT. Refer to
Section 6.1.4, “Enhanced Interrupt
Periodic interrupt status. This bit is set if the PIT issues an interrupt. The PIT issues an interrupt
after the modulus counter counts to zero. PS can be negated by writing a one to it. A write of zero
has no affect.
Reserved
Periodic interrupt enable. If this bit is set, the time base generates an interrupt when the PS bit
is set.
PIT freeze. If this bit is set, the PIT stops while FREEZE is asserted.
Periodic timer enable
0 PIT stops counting and maintains current value
1 PIT continues to decrement
