When a RESET instruction is executed, the MC68340 drives the RESET signal for 512
clock cycles. The SIM40 registers and the module control registers in each internal
peripheral module (DMA, timers, and serial modules) are not affected. All other peripheral
module registers are reset the same as for a hardware reset. The external devices
connected to the RESET signal are reset at the completion of the RESET instruction.
