I2C
The inter-integrated circuit (I2C) controller makes the Z8 Encore! compatible with the I2C
protocol. The I2C controller consists of two bidirectional bus lines, a serial data (SDA)
line and a serial clock (SCL) line. The I2C can operate as a master and/or slave and sup-
ports multimaster bus arbitration.
Internal Precision Oscillator
The Internal Precision Oscillator (IPO) provides a stable, accurate time base without the
requirement for external components. This can reduce system cost in many applications
by eliminating the requirement for external crystals or ceramic resonators. IPO frequency
is 5.5296MHz.
Crystal Oscillator
The on-chip crystal oscillator features programmable gain to support crystals and ceramic
resonators from 32KHz to 20MHz. The oscillator can also be used with clock drivers.
Standard Timer
The 16-bit reloadable timer can be used for timing/counting events and PWM signal gen-
eration. This timer provides a 16-bit programmable reload counter and operate in One-
Shot, Continuous, Gated, Capture, Compare, Capture and Compare, and PWM modes.
This timer can measure velocity from a tachometer wheel or read sensor outputs for rotor
position for brushless DC motor commutation. The standard timer can also be used for
general purpose timing and counting operations.
Interrupt Controller
The Z8FMC16100 Series Flash MCU products support 3 levels of programmable interrupt
priority. The interrupt sources include internal peripherals, general-purpose I/O pins, and
system fault detection.
Reset Controller
The Z8FMC16100 Series Flash MCU can be reset using the RESET pin, power-on reset,
Watch-Dog Timer (WDT), Stop-Mode Recovery, or Voltage Brown-Out (VBO) warning
signal.
On-Chip Debugger
The Z8FMC16100 Series Flash MCU features an integrated On-Chip Debugger (OCD).
The single-pin OCD interface provides a rich set of debugging capabilities, such as read-
