Any change of these bits is signalled via the interrupt-bit (SLCX) in the C/I-DU-channel.
There are two types of generating an interrupt:
– Each toggling of a non-masked TCR1-bit combined with a DUP-counter
– Toggling of the non-masked CFAIL-bit (no filtering by the DUP-counter)
The status information is stored in the TCR1-register by an interrupt or - if there is no
interrupt - before reading this register only.
The HOOK- and the GNK-input are directly filtered by an own DUP-/DUPGNK-counter
too and they are also directly included in the C/I-DU-channel.
Reading the TCR1-register is possible in two ways:
– Reading only TCR1 (TOP-command with LSEL = 0b)
– Reading TCR1 with other TCR-registers (TOP-command with LSEL = 0b)
The first way gives the actual status of all TCR1-inputs if the internal interrupt is not
active and actualizes the TCR1-register.
Is the interrupt active the content of TCR1-register is read and the interrupt is cleared.
The second way gives the content of TCR1-register and nothing will be changed.
The following figure shows the flow diagram of the interrupt logic.
