System Peripherals
8.1.1
PS: Power-saving
The power-saving feature optimizes power consumption, enabling the software to stop the
ARM7TDMI clock (idle mode), restarting it when the module receives an interrupt (or reset). It
also enables on-chip peripheral clocks to be enabled and disabled individually, matching power
consumption and application needs.
8.1.2
AIC: Advanced Interrupt Controller
The Advanced Interrupt Controller has an 8-level priority, individually maskable, vectored inter-
rupt controller, and drives the NIRQ and NFIQ pins of the ARM7TDMI from:
The external fast interrupt line (FIQ)
The three external interrupt request lines (IRQ0 - IRQ2)
The interrupt signals from the on-chip peripherals
The AIC is extensively programmable offering maximum flexibility, and its vectoring features
reduce the real-time overhead in handling interrupts.
The AIC also features a spurious vector detection feature, which reduces spurious interrupt han-
dling to a minimum, and a protect mode that facilitates the debug capabilities.
8.1.3
PIO: Parallel I/O Controller
The AT91FR40162SB has 32 programmable I/O lines. Six pins are dedicated as general-pur-
pose I/O pins. Other I/O lines are multiplexed with an external signal of a peripheral to optimize
the use of available package pins. The PIO controller enables generation of an interrupt on input
change and insertion of a simple input glitch filter on any of the PIO pins.
8.1.4
WD: Watchdog
The Watchdog is built around a 16-bit counter and is used to prevent system lock-up if the soft-
ware becomes trapped in a deadlock. It can generate an internal reset or interrupt, or assert an
active level on the dedicated pin NWDOVF. All programming registers are password-protected
to prevent unintentional programming.
8.1.5
SF: Special Function
The AT91FR40162SB provides registers that implement the following special functions.
Chip Identification
RESET Status
Protect Mode
