4 ON BOARD RESOURCES

4.1

POWER SUPPLY

The three position slide switch (SW6) operates in accordance with the settings given in Table 8.

The Power Indicator LED (red) illuminates when power is applied to the evaluation board

through any of the methods.

NOTE #1: At power-on, the evaluation board preforms an initialization routine (approximately 1 second) during which

all the LEDs (LED1 through LED4) are illuminated. Once the initialization routine has completed the LEDs are turned

off.

NOTE #2: If batteries are loaded into the holder and the board also has power applied via the USB or DC Jack, and the

Power Switch is toggled between the VBAT and either of the VREG postions the device may get stuck in the

initialization routine. If this occurs, simply press the RESETB button.

4.2

RESET

The ZICM2410-EVB3, by default, has the switch labeled 'RESETB' (SW5) connected to the

'RESET#' pin of the ZICM2410 module. When pressed, the ZIC2410 will be reset. Using the

isolation DIP switches (U203:2), SW5 can be disconnected and external circuitry added.

4.3

ISP SWITCH

The 2-position slide switch (SW7) controls the mode of operation, as shown in Figure 4. The

ZIC2410 can be placed into either 'ISP' or 'NORMAL' mode. When placed into ISP mode, the

ZIC2410 is configured for the programming of the internal Flash memory (i.e. a firmware

upgrade). In order to enter ISP mode, the slider switch must be set to 'ISP' and then power

applied to the device (alternatively, if power has already been applied the 'RESETB' pushbutton
