2.1
The Q-SMINT I supports either a serial or a parallel microcontroller interface. For
applications where no controller is connected to the Q-SMINT I microcontroller
interface, register programming is done via the IOM -2 MONITOR channel from a
master device. In such applications the Q-SMINT I operates in the IOM -2 slave mode
(refer to the corresponding chapter of the IOM -2 MONITOR handler).
The interface selections are all done by pinstrapping. The possible interface selections
are listed in
released. For the pin levels stated in the tables the following is defined:
’High’:dynamic pin value which must be ’High’ when the pin level is evaluated
V
•
Table 4
Note: For a selected interface mode which does not require all pins (e.g. address pins)
The microcontroller interface also consists of a microcontroller clock generation at pin
MCLK, an interrupt request at pin INT, a reset input pin RST and a reset output pin
RSTO.
The interrupt request pin INT (open drain output) becomes active if the Q-SMINT I
requests an interrupt.
