INITIAL DELIVERY STATE
When delivered from ST, the PSD device has all
bits in the memory and PLDs set to ’1.’ The PSD
Configuration Register bits are set to ’0.’ The code,
configuration, and PLD logic are loaded using the
Table 35. JTAG Enable Register
Note: 1. The state of Reset (RESET) does not interrupt (or prevent) JTAG operations if the JTAG signals are dedicated by an NVM Config-
