11.0
11.1
The PWR pin is used to reset the ZL50075. When this pin is low, the following functions are performed:
•
•
•
•
11.2
The ZL50075 has two separate power supplies: V
power-up sequence is for V
V
11.3
Upon power up, the ZL50075 should be initialized as follows:
•
•
•
•
•
DD_IO
Asynchronously puts the microprocessor port in a reset state
Tristates all of the output streams (SToA0 - 31, SToB0 - 31)
Preloads all of the registers with their default values (refer to the individual registers for default values)
Clears all internal counters
Assert PWR to low immediately after power is applied
Set the TRST pin low to disable the JTAG TAP controller
Deassert the PWR pin.
Apply the Master Clock Input (CKi0) and Master Frame Pulse Input (FPi0) to the values defined by the
CK_SEL1 - 0 pins
Set the ODE pin low to disable the output streams
