The SYSC includes the Reset Controller (RSTC) and the System Timers (SYST).
The RSTC manages all system resets: external devices reset, processors reset and peripheral
reset.
The sources of reset can be: Power-On, Watch Dog, SW reset, External reset.
The SYST features:
The PMC features two clock sources: Slow Clock Oscillator (32.768 Hz) and Main Oscillator (8
to 20 MHz).
Two dividers, A and B, and two Phase Lock Loops, A and B, allow a wide range of frequencies
to be generated from either the slow clock and/or the main clock.
The PMC provides dedicated clocks toward: ARM926, the AHB Matrix, mAgicV, mAgicV Memo-
ries, the USB, the Ethernet MAC and all Peripherals.
The AIC features:
TWI 1 bi-directional: TWCK
• One 16-bit Period Interval Timer
• One 12-bit key-protected Watchdog Timer
• One 20-bit Free-running Real-time Timer
• Controls the interrupt lines (nIRQ and nFIQ) of ARM926
• Thirty-two individually maskable and vectored interrupt sources
• Programmable Edge-triggered or Level-sensitive Internal Sources
• Programmable Positive/Negative Edge-triggered or High/Low Level sensitive
