scan the status out serially using the standard JTAG channel. See Application Note
AN1153.
TERR indicates if an error has occurred when erasing a sector or programming a byte in
Flash memory. This signal goes Low (active) when an Error condition occurs, and stays Low
until an “ISC_CLEAR” command is executed or a chip Reset (RESET) pulse is received
after an “ISC_DISABLE” command.
TSTAT behaves the same as Ready/Busy described in
TSTAT is High when the PSD module device is in READ mode (primary and secondary
Flash memory contents can be read). TSTAT is Low when Flash memory Program or Erase
cycles are in progress, and also when data is being written to the secondary Flash memory.
TSTAT and TERR can be configured as open-drain type signals during an “ISC_ENABLE”
command.
Security and Flash memory protection
When the Security Bit is set, the device cannot be read on a Device Programmer or through
the JTAG Port. When using the JTAG Port, only a Full Chip Erase command is allowed.
All other Program, Erase and Verify commands are blocked. Full Chip Erase returns the part
to a non-secured blank state. The Security Bit can be set in PSDsoft Express Configuration.
All primary and secondary Flash memory sectors can individually be sector protected
against erasures. The sector protect bits can be set in PSDsoft Express Configuration.
Programming in-circuit using the JTAG
