Low Battery Detector
The low battery detector (LVD) is able to generate an interrupt when the supply voltage
drops below a user-programmable level. The LVD is available on 8-pin devices only.
UART
The UART is full-duplex and capable of handling asynchronous data transfers. The UART
supports 8- and 9-bit data modes and selectable parity. The UART also supports multi-
drop address processing in hardware. The UART baud rate generator (BRG) can be config-
ured and used as a basic 16-bit timer.
Timers
Two enhanced 16-bit reloadable timers can be 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, Capture Restart, Compare, Capture and
Compare, PWM Single Output and PWM Dual Output modes.
Interrupt Controller
The Z8 Encore! XP
®
4K Series products support up to 20 interrupts. These interrupts con-
sist of 8 internal peripheral interrupts and 12 general-purpose I/O pin interrupt sources.
The interrupts have 3 levels of programmable interrupt priority.
Reset Controller
The Z8 Encore! XP
®
4K Series products can be reset using the RESET pin, power-on
reset, Watch-Dog Timer (WDT) time-out, STOP mode exit, or voltage brown-out (VBO)
warning signal. The RESET pin is bi-directional, meaning it functions as reset source as
well as a reset indicator.
On-Chip Debugger
The Z8 Encore! XP
®
4K 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 Flash memory, setting breakpoints and executing code. A single-pin
interface provides communication to the OCD.
