7.13 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 ten BCLK
cycles after V
on reset operation, illustrating the relationships among V
signals. CLK is required to be stable by the time V
ification. CLK should start oscillating as V
internal to the part caused by the random manner in which internal flip-flops power-up. RSTI
is internally synchronized for two BCLKs before being used and must meet the specified
