Reading received telegrams
When the KL6021-0023 has received new telegrams it indicates this by setting the bit SB.2 [} 26] in the
status byte to 1. Reading out received telegrams is initiated through bit CB.0 [} 26] in the control byte being
inverted by the higher-level controller. The change from 0 to 1 or from 1 to 0 always causes the next
telegram in the memory to be displayed in the process data. The value of the bit CB.0 [} 26] is adopted by
SB.0 [} 26] as acknowledgement.
