Microchip Technology MA320002 Data Sheet

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 Secondary Oscillator (S

OSC

)

for real-time clock applications. The following modes
are supported:

• Synchronous Internal Timer

• Synchronous Internal Gated Timer

• Synchronous External Timer

• Asynchronous External Timer

• 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 S

OSC

 

to function as a Real-Time Clock (RTC)

Note 1: This data sheet summarizes the features

of the PIC32MX3XX/4XX family of
devices. It is not intended to be a compre-
hensive reference source. To comple-
ment the information in this data sheet,
refer to Section 14. “Timers” (DS61105)
of the “PIC32 Family Reference Manual”,
which is available from the Microchip web
site (

).

2: Some registers and associated bits

described in this section may not be
available on all devices. Refer to
