used as Baud Rate Generator (BRG) when UART is enabled and configured as basic 16-
bit timers when UART is disabled.
1.4.16. Multi-Channel Timer
The multi-channel timer has a 16-bit up/down counter and a 4-channel Capture/Compare/
PWM channel array. This timer enables the support of multiple synchronous Capture/
Compare/PWM channels based on a single timer.
1.4.17. Interrupt Controller
The Z8 Encore! XP F1680 Series products support up to thirty-one interrupt sources with
twenty-four interrupt vectors. These interrupts consist of up to fifteen internal peripheral
interrupts and up to sixteen GPIO pin interrupts. The interrupts have three levels of pro-
grammable-interrupt priority.
1.4.18. Reset Controller
The F1680 Series MCU is reset using the RESET pin, POR, WDT time-out, STOP Mode
exit, or VBO warning signal. The RESET pin is bidirectional, that is, it functions as reset
source as well as a reset indicator.
1.4.19. On-Chip Debugger
The F1680 Series MCU features an integrated OCD. The OCD provides a rich-set of
debugging capabilities, such as reading and writing registers, programming Flash memory,
setting breakpoints and executing code. The OCD uses one single-pin interface for com-
munication with an external host.
1.4.20. Direct LED Drive
The Port C pins also provide a current synchronized output capable of driving an LED
without requiring any external resistor. Up to eight LEDs are driven with individually pro-
grammable drive current level from 3 mA to 20 mA.
