of 0x4 to the

GPTM Configuration (GPTMCFG)

register (see page 976). In the following sections,

the variable "

n

" is used in bit field and register names to imply either a Timer A function or a Timer

B function. Throughout this section, the timeout event in down-count mode is 0x0 and in up-count
mode is the value in the

GPTM Timer n Interval Load (GPTMTnILR)

and the optional

GPTM Timer

n Prescale (GPTMTnPR)

registers, with the exception of RTC mode.

13.3.3.1

One-Shot/Periodic Timer Mode

The selection of one-shot or periodic mode is determined by the value written to the

TnMR

field of

the

GPTM Timer n Mode (GPTMTnMR)

register (see page 977). The timer is configured to count

up or down using the

TnCDIR

bit in the

GPTMTnMR

register.

When software sets the

TnEN

bit in the

GPTM Control (GPTMCTL)

register (see page 986), the

timer begins counting up from 0x0 or down from its preloaded value. Alternatively, if the

TnWOT

bit

is set in the

GPTMTnMR

register, once the

TnEN

bit is set, the timer waits for a trigger to begin

counting (see “Wait-for-Trigger Mode” on page 968). Table 13-4 on page 960 shows the values that
are loaded into the timer registers when the timer is enabled.

When the timer is counting down and it reaches the timeout event (0x0), the timer reloads its start
value from the

GPTMTnILR

and the

GPTMTnPR

registers on the next cycle. When the timer is

counting up and it reaches the timeout event (the value in the

GPTMTnILR

and the optional

GPTMTnPR

registers), the timer reloads with 0x0. If configured to be a one-shot timer, the timer

stops counting and clears the

TnEN

bit in the

GPTMCTL

register. If configured as a periodic timer,

the timer starts counting again on the next cycle.

In periodic, snap-shot mode (

TnMR

field is 0x2 and the

TnSNAPS

bit is set in the

GPTMTnMR

register), the value of the timer at the time-out event is loaded into the

GPTMTnR

register and the

value of the prescaler is loaded into the

GPTMTnPS

register. The free-running counter value is

shown in the

GPTMTnV

register. In this manner, software can determine the time elapsed from the

interrupt assertion to the ISR entry by examining the snapshot values and the current value of the
free-running timer. Snapshot mode is not available when the timer is configured in one-shot mode.

In addition to reloading the count value, the GPTM can generate interrupts, CCP outputs and triggers
when it reaches the time-out event. The GPTM sets the

TnTORIS

bit in the

GPTM Raw Interrupt

Status (GPTMRIS)

register (see page 996), and holds it until it is cleared by writing the

GPTM

Interrupt Clear (GPTMICR)

register (see page 1002). If the time-out interrupt is enabled in the

GPTM

Interrupt Mask (GPTMIMR)

register (see page 993), the GPTM also sets the

TnTOMIS

bit in the

GPTM Masked Interrupt Status (GPTMMIS)

register (see page 999). The time-out interrupt can be

disabled entirely by setting the

TnCINTD

bit in the

GPTM Timer n Mode (GPTMTnMR)

register. In

this case, the

TnTORIS

bit does not even set in the

GPTMRIS

register.

By setting the

TnMIE

bit in the

GPTMTnMR

register, an interrupt condition can also be generated

when the Timer value equals the value loaded into the

GPTM Timer n Match (GPTMTnMATCHR)

and

GPTM Timer n Prescale Match (GPTMTnPMR)

registers. This interrupt has the same status,

masking, and clearing functions as the time-out interrupt, but uses the match interrupt bits instead
(for example, the raw interrupt status is monitored via

TnMRIS

bit in the
