18 Timers and PWM
The Timer and Pulse Width Modulation (PWM) block allows individual control of the
frequency and duty cycle of two output signals. The PWM block also supports use as a
Timer block for the purposes of generating periodic interrupts.
18.1 Signal Descriptions
Please see Chapter 2, “Physical Interfaces” for additional details.
The signal description table has the following headings:
• Signal Name: The name of the signal/pin
• Direction: The buffer direction can be either input, output, or I/O
(bidirectional)
• Type: The buffer type found in Chapter 4, “Electrical Characteristics”
• Description: A brief explanation of the signal’s function

PWM[1] O /
IOVDD
Output 1:
PWM Output 1
NOTE: Signal Names are preliminary and are subject to changes when the “Physical Interfaces”
Chapter is populated.
18.2 Features
The following is a list of the PWM features:
• 2 Counters capable of operating in PWM Mode or Timer Mode
• PWM Mode
o Configurable High and Low times for each PWM Output
 Minimum High and Low time of 2 32MHz clock
periods
(8MHz)
 Maximum High and Low time of 2^32 32MHz clock
periods
(< 1Hz)
o High and Low time granularity of a single 32MHz clock period
o Interrupt generation always on both the rising and falling edges of the
PWM Output
o Interrupt Control per PWM Output:
 Interrupt Generation only on both edges of the PWM
Output
