6.12.4.1 Pin description
6.13.1 Peripheral subsystem clock description
6.13 Peripheral subsystem
The event router allows the event source to be defined, its polarity and activation type to
be selected and the interrupt to be masked or enabled. The event router can be used to
start a clock on an external event.
The vectored interrupt controller inputs are active HIGH.
The event router module in the LPC2939 is connected to the pins listed below. The pins
are combined with other functions on the port pins of the LPC2939.
pins connected to the event router and three additional internal signals.
Table 15.
The peripheral subsystem is clocked by a number of different clocks:
