... AT572D740 14 tional banked working registers, r8_fiq to r12_fiq, to enhance interrupt processing speed. The ARM7TDMI processor operates in little-endian mode. To speed-up critical routine execution or critical data segment access, the ARM7 is equipped with 32 Kbyte of zero wait states on-chip memory. The ARM system has two buses. The main bus is the ASB (ARM System Bus). The APB (ARM Peripheral Bus) is designed for accesses to on-chip peripherals ...
