... The System Controller manages the reset of the entire system and integrates a clock generator made oscillator and a PLL. The AT75C221 architecture is made up of two Advanced System Buses, the ARM ASB and the MAC ASB. Both handle a single memory space. The ARM ASB handles the access requests of the ARM7TDMI and the PDC. It handles also the access requests coming from the MAC ASB ...

... ASB bandwidth, ensuring that the ARM7TDMI can perform at its maxi- mum speed while the Ethernet traffic goes through the Frame Buffer. The AT75C221 can boot in several ways; including from internal boot software and a hardware connection of DataFlash. When the ARM7TDMI processor is released from reset, it basically attempts a fetch from address 0x00000000 ...

... External sources can be programmed to be positive- or negative-edge triggered or high- or low-level sensitive. The AT75C221 integrates 24 programmable I/O pins. Each pin can be programmed as an input or an output. Each pin can also generate an interrupt. The programmable I/O is implemented as two blocks, called PIO A and PIO B, 32 and 16 pins each, respectively. ...
