What is the benefit of having the Mode[0:2] pins on the ML674000 as opposed to handling these tasks through software?
The Mode[0:2] pins of the processor handle the enabling and disabling of the DRAM controller and A-to-D converter of the processor. By disabling these hardware blocks through hardware, the power source to these blocks is cut off and hence power consumption of the ARM processor will drop significantly. Mode[0:2] pins are also tied to additional functionalities such as enabling and disabling the Primary and Secondary functions of Processor pins. 17. What is the MIPs performance of Oki Oki’s ARM MCUs are based on the ARM7TDMI core. According to ARM Ltd. the figures for calculating the VAX MIPS for ARM are as follows: The maximum performance of the ARM7 family is 0.9 Dhrystone VAX MIPS per MHz. The maximum performance of the ARM9 family is 1.1 Dhrystone VAX MIPS per MHz. This figure assumes an ARM core running from 32-bit wide zero-wait state memory. Oki’s ARM MCUs have a 16-bit external data bus. This features reduces power consumption, reduces the package size and the cost of the package
