Note:
This data sheet summarizes the features
of the PIC32MX3XX/4XX family of
devices. It is not intended to be a compre-
hensive reference source. Refer to the
“PIC32MX Family Reference Manual”
(DS61132) for a detailed description of this
peripheral.
This family of PIC32MX devices features one
synchronous/asynchronous 16-bit timer that can oper-
ate as a free-running interval timer for various timing
applications and counting external events. This timer
can also be used with the Low-Power Secondary
Oscillator, SOSC, for real-time clock applications. The
following modes are supported:
• Synchronous Internal Timer
• Synchronous Internal Gated Timer
• Synchronous External Timer
• Asynchronous External Timer
13.1 Additional Supported Features
• Selectable clock prescaler
• Timer operation during CPU Idle and Sleep mode
• Fast bit manipulation using CLR, SET and INV
registers
• Asynchronous mode can be used with the
Low-Power Secondary Oscillator to function as a
Real-Time Clock (RTC).
