# encode\_rs8(9)

Calculate the parity for data values (8bit data width)

## NAME

encode\_rs8 - Calculate the parity for data values (8bit data width)

## SYNOPSIS

**int encode\_rs8(struct rs\_control \*** *rs***, uint8\_t \*** *data***, int** *len***, uint16\_t \*** *par***, uint16\_t** *invmsk***);**

## ARGUMENTS

*rs*

the rs control structure

*data*

data field of a given type

*len*

data length

*par*

parity data, must be initialized by caller (usually all 0)

*invmsk*

invert data mask (will be xored on data)

## DESCRIPTION

The parity uses a uint16\_t data type to enable symbol size \> 8. The calling code must take care of encoding of the syndrome result for storage itself.
