ARM9 microcontroller with CAN and LIN

Functional description
7.1 Reset, debug, test and power description
7.1.1
Reset and power-up behavior
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 11
for trip levels of the internal power-up reset circuit
1
. See
Section 12
for characteristics of the several start-up and initialization times.
Table 4
shows
the reset pin.
Table 4.
Symbol
RSTN
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
re-program 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.
7.1.2
Reset 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.
