===== Library =====

LIB\CORE

===== Version =====

V1.0

===== Description =====

The block is a register of up to 16 real values. The values are stored at the rising (**//clockrising//**) or falling (**//clockfalling//**) edge of the input signal.

===== Inputs =====

|Input          |Type                           |Description                                                                      |Default value|
|CLOCKRISING    |BOOL                           |Rising edge copies inputs to outputs.                                            |False        |
|CLOCKFALLING   |BOOL                           |Falling edge copies inputs to outputs.                                           |False        |
|INITIALIZE     |BOOL                           |If //initialize// = true, then the //initvalue// is written to all outputs//\\ //|False        |
|IN             |[[en:mervis-ide:35-help:035-software_basic:060-libraries:015-proto|MULTIIOREAL]]|Input array from the **//helper_multiinreal//** block                            |[0,0,...,0]  |
|INITVALUE      |REAL                           |The value set to all outputs when //initialize// = true.                         |0            |
|IN0,IN1,..,IN15|REAL                           |The inputs as individual values                                                  |             |

===== Outputs =====

|Output            |Type                           |Description                                         |
|OUT               |[[en:mervis-ide:35-help:035-software_basic:060-libraries:015-proto|MULTIIOREAL]]|Input array to the **//helper_multioutreal//** block|
|OUT0,OUT1,..,OUT15|REAL                           |The outputs as individual values                    |

===== Function =====

The **//clockrising//** input reacts on the rising edge of the input signal which causes the inputs to propagate to the outputs. Similarly, the **//clockfalling//** input reacts on the falling edge of the input signal which causes the inputs to propagate to the outputs. If **//initialize//** = true, the **//initvalue//** is written to the outputs. Inputs and outputs may be connected in two ways, either through a multireal type to the //in// input, or individually to inputs //in0,in1,...//.

===== Application example =====

{{:en:mervis-ide:35-help:b105_example.png}}

A rising edge on the //bool1// input copies the inputs to the outputs, or makes a "snapshot" of the input vector which is available at the outputs. Inputs and outputs are connected individually here, rather than using a multireal variable.
