count down to zero and can be used to generate regular periodic interrupts. Each timer has the following
four configuration and control registers:
The timer frequency should be written to the TFRR. (All of the timers operate at this frequency.) Refer to
Section 10.3.2.1, “Timer Frequency Reporting Register (TFRR),”
Timer interrupts are all edge-triggered interrupts. If a timer period expires while a previous interrupt from
the same source is pending or in-service, the subsequent interrupt is lost.
The timer control register (TCR) provides users with the ability to create timers larger than the 31-bit
global timers. The option also exists to change the timer frequency by setting the appropriate fields of the
TCR. See
10.4.8
The PIC unit is reset by a device power-on reset (POR) or by software that sets the GCR[RST] bit. Both
of these actions cause the following:
The GCR[RST] bit is automatically cleared when the reset sequence is complete.

This section contains initialization and application information for the PIC.

The following sections contain information about programming PIC registers.
Freescale Semiconductor
Global timer current count register (GTCCRn)
Global timer base count register (GTBCRn)
Global timer vector-priority register (GTVPRn)
Global timer destination register (GTDRn)
All pending and in-service interrupts are cleared.
All interrupt mask bits are set.
Polarity, sense, external pin, critical interrupt, and activity fields are reset to default values.
PIR, TFRR, TCR, MER, MSR, and MSGR0–3 are cleared.
MSG and timer destination fields are set.
The IPI dispatch registers are cleared.
All timer base count values are reset to zero and count inhibited.
The CTPR[TASKP] is reset to 0xF, thus disabling interrupt delivery to the processor.
The spurious interrupt vector resets to 0xFFFF.
The PMMRs are reset to 0xFFFF.
The PIC defaults to the pass-through mode (GCR[M] = 0).
All other registers remain at their pre-reset programmed values.
