## 5.1. OpenECU blockset reference

The following sub-sections describe the layout and working of each OpenECU
block. Each sub-section follows the same form, including diagrams of the block
and its mask, a description of its functionality and a description of the
block's inports, outports and any parameters.

Some inports, outports and parameters have a valid numerical range or
size of vector. If so, the range and size information is given beside the
object's description using internal notation.

**Table 5.1. Interval notation**

Notation | Range |
---|

(x, y) | x < value < y |

[x, y) | x <= value < y |

(x, y] | x < value <= y |

[x, y] | x <= value <= y |

Some objects are not clipped to a range but folded into a range
using modulo arithmetic and where this occurs, the description
includes details.
