7.1.1 Reset and power-up behavior
7.1.2 Reset strategy
7.1 Reset, debug, test and power description
The LPC2917/19 contains external reset input and internal power-up reset circuits. This
ensures that a reset is extended internally until the oscillators and flash have reached a
stable state. See
Section 12
the reset pin.
Table 4.
At activation of the RST_N 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
reprogram the source for the BASE_SYS_CLK to be the crystal oscillator instead of the
Low-Power Ring Oscillator (LP_OSC). This is required because the clock rate when
running at LP_OSC speed is too low for the external debugging environment.
The LPC2917/19 contains a central module, the Reset Generation Unit (RGU) in the
Power, Clock and Reset 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.
