Analog power and ground. VDDA is nominally 1.8V for this device. It is recommended

that this supply voltage be filtered to remove any digital noise that may be present on

the supply.

RESETB

The RESETB pin is an open-drain, bidirectional pin. At power up, it is configured

strictly as an input pin. Setting RCSR[DR] (Reset Control & Status Register “Drive

Reset” bit) to one will cause the RESET function to become bidirectional. Using this

feature, FXLC95000CL can reset external devices whenever it is reset for any purpose

other than power-on-reset.

Slave I2C: SDA0, SCL0

Slave I2C data and clock signals. FXLC95000CL may be controlled via this serial port

or via the slave SPI interface. At reset, SDA0 and SCL0 are open-drain, bidirectional in

input mode, with the pullup resistor disabled.

Master I2C: SDA1, SCL1

Master I2C data and clock signals. Because the FXLC95000CL contains a 32-bit

ColdFire V1 CPU, it is fully capable of mastering other devices in the system via this

serial port.

State at reset: active. SCL1 and SDA1 are configured on pins 1 and 2, respectively. The

alternate functionality on these pins is RGPIO14 and RGPIO15.

Analog-to-Digital Conversion: AN0, AN1

The on-chip ADC can be used to perform a differential analog-to-digital conversion

based upon the voltage present across pins AN0(-) and AN1(+). Conversions for these

pins are at the same Sample Data Rate (SDR) as the MEMS transducer signals.

State at reset: Inactive. AN[1:0] are secondary functions on RGPIO[7:6], which own the

pins at reset.

Rapid General Purpose I/O: RGPIO[15:0]

The ColdFire V1 CPU has a feature called “Rapid GPIO” or RGPIO. This is a 16-bit

input/output port with single-cycle write, set, clear, and toggle functions available to the

CPU. The FXLC95000CL brings out all 16 bits of that port as pins of the device.

State at reset:

• RGPIO[15:14]: inactive. SDA1 and SCL1 own the pin at reset.
