(SDA) line, and a serial clock (SCL) line.
The Serial Peripheral Interface (SPI) allows the Z8 Encore! XP to exchange data between
other peripheral devices such as EEPROMs, A/D converters, and ISDN devices. The SPI
is a full-duplex, synchronous, and character-oriented channel that supports a four-wire
interface.
Two 16-bit reloadable timers are used for timing/counting events or for motor control
operations. These timers provide a 16-bit programmable reload counter and operate in
One-Shot, Continuous, Gated, Capture, Compare, Capture and Compare, and PWM
modes.
Z8 Encore! XP
sist of 7 internal peripheral interrupts and 11 GPIO pin interrupt sources. The interrupts
have 3 levels of programmable interrupt priority.
Z8 Encore! XP F0822 Series products are reset using the RESET pin, POR, WDT, STOP
mode exit, or VBO warning signal.
Z8 Encore! XP F0822 Series products feature an integrated On-Chip Debugger (OCD).
The OCD provides a rich-set of debugging capabilities, such as, reading and writing regis-
ters, programming the Flash, setting breakpoints, and executing code. A single-pin inter-
face provides communication to the OCD.
