7.10 RESET OPERATION
An external device asserts the reset input signal (RSTI) to reset the processor. When
power is applied to the system, external circuitry should assert RSTI for a minimum of 10
BCLK cycles after V
the power-on reset operation, illustrating the relationships among V
selects, and bus signals. The BCLK and PCLK clock signals are required to be stable by
the time V
