Data Sheet
Note: ST0Vxy and ACKxy are useful for synchronizing microcontroller accesses and
17.5.3.8 ASTI - Acknowledge Synchronous Transfer Interrupt
Value after reset: 00
ASTI
ACKxy
After a STIxy interrupt the microcontroller has to acknowledge the interrupt by setting the
corresponding ACKxy bit.
0: No activity is initiated
1: Sets the acknowledge bit ACKxy for a STIxy interrupt
17.5.3.9 MSTI - Mask Synchronous Transfer Interrupt
Value after reset: FF
MSTI
For the MSTI register following logical states are applied:
0: Interrupt is not masked
1: Interrupt is masked
STOVxy
By masking the STOV bits the number and time of the STOV interrupts for a certain
enabled STIxy interrupt can be controlled. For an enabled STIxy the own STOVxy is
generated when the STOVxy is enabled (MSTI.STIxy and MSTI.STOVxy = ’0’).
Additionally all other STOV interrupts of which the corresponding STI is disabled
(MSTI.STI = ’1’ and MSTI.STOV = ’0’) are generated.
