ROM Library Function Guide
Description
Measures the ambient air pressure or acceleration
Measures the ambient air pressure
Scale pressure into a single byte for RF transmission
Measures the acceleration
Measures the ambient temperature
Measures the raw temperature
Compensates raw temperature data
Measures the battery voltage
These three functions perform a Battery Voltage
measurement during an RF Transmission.
Returns the delta of ADC test measurements

Enables the Crystal Oscillator
Stops the Crystal Oscillator
Evaluates Crystal Resonator signal
Tunes the VCO frequency
Calibrates the Interval Timer precounter
Calibrates the LF baudrate divider
Multiplies two signed values (16 bit * 16 bit)
Divides two unsigned values (32 bit : 32 bit)
Divides two unsigned values (16 bit : 16 bit)
Calculates an 8 Bit CRC with polynom 83
Calculates an 8 Bit CRC with poylnom 97
Returns the unique device ID

Erases the FLASH user configuration sector
Writes one FLASH line (32 Bytes) in the FLASH user
configuration sector
Writes one FLASH line (32 Bytes) in the FLASH
Code Sector 0.
Sets the Lockbyte to protect the User Configuration
sector
Evaluates the ECC result bit
