7. Multifunctional PWM
The family devices support both 8- and 16-bit PWM operations. Choosing between the time base counter
output and the overflow from an 8-bit auto-reload time as the PWM counter clock source provides a great
number of possibilities over a broad frequency range. The 16-bit PWM configuration supports a high-speed
synchronization mode that generates a high-precision output signal with less ripple suitable for
digital-to-analog applications.
8. Programmable pull-up resistors
Building the pull-up resistors into the chip contributes overall design compactness.
Making them programmable on a per-bit basis allows complete flexibility in circuit board layout and system
design. These programmable pull-up resistors are available for all I/O pins except ports that have specific
functions such as oscillator connection pins.
9. High-speed bus interface
The interface to external devices uses separate data and address buses.
This arrangement permits a rapid bus access for controlling the system from the microcontroller.
10. A variety of external interrupts
There are a total of seven interrupt channels for use in communicating with external devices; six channels for
maskable interrupts and one channel for non-maskable interrupts.
