When a $$''CALL$$ $$addr'$$ instruction is executed, the $$CPU$$ carries out the following sequential operations internally.

Note:
$$(R)$$ means content of register $$R$$
$$\left( {\left( R \right)} \right)$$ means content of memory locating pointed by $$R$$
$$PC$$ means Program Counter
$$SP$$ means Stack Pointer

A
$$\eqalign{ & \left( {SP} \right)\,\,\,\,\,\,\,incremented \cr & \left( {PC} \right)\,\,\,\,\,\, \leftarrow \left( {Addr} \right) \cr & \left( {\left( {SP} \right)} \right) \leftarrow \left( {PC} \right) \cr} $$
B
$$\eqalign{ & \left( {PC} \right)\,\,\,\,\,\, \leftarrow \left( {Addr} \right) \cr & \left( {\left( {SP} \right)} \right) \leftarrow \left( {PC} \right) \cr & \left( {SP} \right)\,\,\,\,\,\,\,incremented \cr} $$
C
