Freescale Semiconductor 4-7

Again referring to Figure 4-3, a number of zero-ohm resistors are provided to isolate different circuits and

to allow current measurement:

• VCC (main 1323x-RCM supply) - resistor R35

• V_LED (all LEDs supply) - resistor R36

• V_TPD (touchpad supply) - resistor R37

• V_ACC (accelerometer supply) - resistor R40

• V_BUZ (buzzer supply) - resistor R42

• V_MRB (1323x-MRB supply) - resistor R43

4.2.2 GPIO Connection to 1323x-MRB

IO Connectors J8 and J9 (see Figure 4-1) are receptacles that accept the 1323x-MRB pin headers to mount

the daughter card. Figure 2-1 shows the 1323x-RCM with the 1323x-MRB mounted. Receptacles J8 and

J9 connect to the MC13233 GPIO.

To provide better access and versatility to the GPIO, a secondary set of pin headers P1 and P2 is connected

in series with the IO signals:

• Jumpers must be installed on P1 and P2 to connect 1323x-RCM peripherals and functions

• The pin headers provide direct access for connecting custom circuitry to the GPIO

• Power and ground to primary connectors J8 and J9 are not enabled though the pin headers

Figure 4-4 shows IO Header P1 andP2 pin mapping.

• The input voltage range reflects the usable range of

alkaline cells and the voltage drop incurred by the diode

isolation circuit.

• The battery source is disabled if another source is

connected

The minimum operating battery voltage is determined by use model, see Note, Section 4.2.1, “Power Management”
