System Peripherals
A complete memory map is shown in Figure 8-1 on page 17.
9.1
Reset Controller
Two reset input lines (NRST and NTRST) providing, respectively:
Initialization of the User Interface registers (defined in the user interface of each peripheral)
and:
– Sample the signals needed at bootup
– Compel the processor to fetch the next instruction at address zero
Initialization of the embedded ICE TAP controller
9.2
Advanced Interrupt Controller
Controls the interrupt lines (nIRQ and nFIQ) of an ARM Processor
Thirty-two individually maskable and vectored interrupt sources
– Source 0 is reserved for the Fast Interrupt Input (FIQ)
– Source 1 is reserved for system peripherals (ST, RTC, PMC, DBGU…)
– Source 2 to Source 31 control thirty embedded peripheral interrupts or external
interrupts
– Programmable Edge-triggered or Level-sensitive Internal Sources
– Programmable Positive/Negative Edge-triggered or High/Low Level-sensitive
External Sources
8-level Priority Controller
– Drives the Normal Interrupt of the processor
– Handles priority of the interrupt sources 1 to 31
– Higher priority interrupts can be served during service of lower priority interrupt
Vectoring
– Optimizes Interrupt Service Routine Branch and Execution
– One 32-bit Vector Register per interrupt source
– Interrupt Vector Register reads the corresponding current Interrupt Vector
Protect Mode
– Easy debugging by preventing automatic operations
General Interrupt Mask
– Provides processor synchronization on events without triggering an interrupt
9.3
Power Management Controller
Optimizes the power consumption of the whole system
Embeds and controls:
– One Main Oscillator and One Slow Clock Oscillator (32.768Hz)
– Two Phase Locked Loops (PLLs) and Dividers
– Clock Prescalers
Provides:
– the Processor Clock PCK
