Table 24. Registers Reset Values
Table 25. I/O Pin Status During Reset and Standby Mode
12.1 Reset Input
The reset input to the PSD4XX (RESET) is an active low signal which resets some of the
internal devices and configuration registers. The Timing Diagram in the AC/DC
characterization section shows the reset signal timing requirement. The active low range
has a minimum T1 duration. After the rising edge of RESET, the PSD4XX remains in
reset during T2 range. (See Figure 48). The PSD4XX must be reset at power up before it
can be used.
12.2 ZPLD and Memory During Reset
While the Reset Input is active, the ZPLD generates outputs as defined in the PSDabel
equations. The EPROM and SRAM blocks respond to the microcontroller bus cycle during
reset, but the data is not guaranteed.
12.3 Register Values During and After Reset
Table 24 summarizes the status of the volatile register values during and after reset.
The default values of the volatile registers are “0” after reset.
12.4 ZPLD Macrocell Initialization
The D flip flops in the macrocells in the GPLD can be cleared by:
t A product term (.RE) defined by the user in PSDabel, or
t The MACRO-RST (Reset) input, enabled and defined in PSDabel.
