1.2.13
General Purpose Timer (GPT)
The general purpose timer (GPT) is a four-channel timer module consisting of a 16-bit programmable counter driven by a
seven-stage programmable prescaler. Each of the four channels can be configured for input capture or output compare.
Additionally, channel three, can be configured as a pulse accumulator.
A timer overflow function allows software to extend the timing capability of the system beyond the 16-bit range of the counter.
The input capture and output compare functions allow simultaneous input waveform measurements and output waveform
generation. The input capture function can capture the time of a selected transition edge. The output compare function can
generate output waveforms and timer software delays. The 16-bit pulse accumulator can operate as a simple event counter or a
gated time accumulator.
1.2.14
Periodic Interrupt Timers (PIT0 and PIT1)
The two periodic interrupt timers (PIT0 and PIT1) are 16-bit timers that provide interrupts at regular intervals with minimal
processor intervention. Each timer can count down from the value written in its PIT modulus register or it can be a free-running
down-counter.
1.2.15
Real-Time Clock (RTC)
The Real-Time Clock (RTC) module maintains the system (time-of-day) clock and provides stopwatch, alarm, and interrupt
functions. It includes full clock features: seconds, minutes, hours, days and supports a host of time-of-day interrupt functions
along with an alarm interrupt.
1.2.16
Pulse-Width Modulation (PWM) Timers
The MCF52211 has an 8-channel, 8-bit PWM timer. Each channel has a programmable period and duty cycle as well as a
dedicated counter. Each of the modulators can create independent continuous waveforms with software-selectable duty rates
from 0% to 100%. The timer supports PCM mode, which results in superior signal quality when compared to that of a
conventional PWM. The PWM outputs have programmable polarity, and can be programmed as left aligned outputs or center
aligned outputs. For higher period and duty cycle resolution, each pair of adjacent channels ([7:6], [5:4], [3:2], and [1:0]) can
be concatenated to form a single 16-bit channel. The module can, therefore, be configured to support 8/0, 6/1, 4/2, 2/3, or 0/4
8-/16-bit channels.
1.2.17
Software Watchdog Timer
The watchdog timer is a 32-bit timer that facilitates recovery from runaway code. The watchdog counter is a free-running
down-counter that generates a reset on underflow. To prevent a reset, software must periodically restart the countdown.
1.2.18
Backup Watchdog Timer
The backup watchdog timer is an independent 16-bit timer that, like the software watchdog timer, facilitates recovery from
runaway code. This timer is a free-running down-counter that generates a reset on underflow. To prevent a reset, software must
periodically restart the countdown. The backup watchdog timer can be clocked by either the relaxation oscillator or the system
clock.
1.2.19
Phase-Locked Loop (PLL)
The clock module contains a crystal oscillator, 8 MHz on-chip relaxation oscillator (OCO), phase-locked loop (PLL), reduced
frequency divider (RFD), low-power divider status/control registers, and control logic. To improve noise immunity, the PLL,
