7.1.1Reset and power-up behavior
The LPC2917/19 contains external reset input and internal

Symbol | Direction | Description |
RSTN | in | external reset input, active LOW; pulled up internally |
|
|
|
At activation of the RSTN pin the JTAGSEL pin is sensed as logic LOW. If this is the case the LPC2917/19 is assumed to be connected to debug hardware, and internal circuits
7.1.2Reset strategy
The LPC2917/19 contains a central module, the Reset Generator Unit (RGU) in the Power, Clock and Reset Control Subsystem (PCRSS), which controls all internal reset signals towards the peripheral modules. The RGU provides individual reset control as well as the monitoring functions needed for tracing a reset back to source.
