P <pause>

Pauses the execution of the script for the time in milliseconds described by pause. This

argument must be an integer value (decimal notation).

SECTION_BEGIN <n_iterations> /SECTION END

Defines a section of code that has to be cycled n_iteration times (decimal notation).

RW <address> <value>

Writes values into the I2C register address (hexadecimal notation).

RR <address>

Reads the I2C register address (hexadecimal notation).

RCMP <address> <value>

Reads the I2C register address and compares it with value (hexadecimal notation).

CWA <address> <coeff 1> <coeff 2> <coeff 3> <coeff 4> <coeff 5>

Writes all five coefficients of a biquadratic filter at the location address (hexadecimal

notation).

CWAF <address> <coeff 1> <coeff 2> <coeff 3> <coeff 4> <coeff 5>

The same as CWA (floating point notation).

CW1 <address> <coeff>

Writes a single coefficient (hexadecimal notation).

CW1F <address> <coeff>

The same as CW1 (floating point notation).

CR1 <address>

Reads a single coefficient located at address (hexadecimal notation).

CRA <address>

Reads five consecutive coefficients starting from location address (hexadecimal notation).

CCMP1 <address> <coeff>

Reads the coefficient located at address and compares it with coeff (hexadecimal notation).

CCMPA <address> <coeff 1> <coeff 2> <coeff 3> <coeff 4> <coeff 5>

Reads five consecutive coefficients starting from location address and compares them with

coeff 1, …, coeff 5 (hexadecimal notation).

APWLINK_INIT_ADC

Initializes the APWLink onboard ADC (see AN4118, “APWLink™ USB interface board for

Sound Terminal® demonstration boards” for further information).
