3.11 Connecting the Emulator Port Pins
Even when the emulator is not used, small shunt capacitors to ground (22 pF) should be used for
protection from EMI as illustrated in Figure 17 . Production boards should have the ICE_E pin connected
to ground.

3.12 Flash Programming
Operational or test code can be programmed into the Flash memory using either an in-circuit emulator or
the Flash Programmer Module (TFP2) available from Maxim. The Flash programming procedure uses
the E_RST, E_RXTX, and E_TCLK pins.
3.13 MPU Firmware Library
Any applications-specific MPU functions mentioned above are available from Maxim as a standard ANSI
C library and as ANSI “C” source code. Sample application code using the measurement library is pre-
programmed in Evaluation Kits for the 78M6618 IC and can be pre-programmed into engineering IC
samples for system evaluation. Application code allows for quick and efficient evaluation of the IC
without having to write firmware or having to purchase an in-circuit emulator (ICE). A Software Licensing
Agreement (SLA) can be signed to receive either the source Flash HEX file for use in a production
environment or source code and SDK documentation for modification.
3.14 Crystal Oscillator
The oscillator drives a standard 32.768 kHz watch crystal. The oscillator has been designed specifically
to handle these crystals and is compatible with their high impedance and limited power handling
capability. Good layouts will have XIN and XOUT shielded from each other.
Since the oscillator is self-biasing, an external resistor must not be connected across the crystal.
