9.6.1 Standard JTAG Signals (cont.)
The PSD813F1 supports JTAG In-System-Configuration (ISC) commands, but not
Boundary Scan. A definition of these JTAG-ISC commands and sequences are defined in a
supplemental document available from ST. ST
’
s PSDsoft software tool and FlashLink JTAG
programming cable implement these JTAG-ISC commands. This document is needed only
as a reference for designers who use a FlashLink to program their PSD813F1.
9.6.2 JTAG Extensions
TSTAT and TERR are two JTAG extension signals enabled by an
“
ISC_ENABLE
”
command received over the four standard JTAG pins (TMS, TCK, TDI, and TDO). They are
used to speed programming and erase functions by indicating status on PSD pins instead
of having to scan the status out serially using the standard JTAG channel. See Application
Note 54.
TERR will indicate if an error has occurred when erasing a sector or programming a byte in
Flash memory. This signal will go low (active) when an error condition occurs, and stay
low until an
“
ISC_CLEAR
”
command is executed or a chip reset pulse is received after an
“
ISC-DISABLE
”
command. TERR does not apply to EEPROM.
TSTAT behaves the same as the Rdy/Bsy signal described in section 9.1.1.2. TSTAT will be
high when the PSD813F1 device is in read array mode (Flash memory and EEPROM
contents can be read). TSTAT will be low when Flash memory programming or erase cycles
are in progress, and also when data is being written to EEPROM.
TSTAT and TERR can be configured as open-drain type signals during an
“
ISC_ENABLE
”
command. This facilitates a wired-OR connection of TSTAT signals from several PSD813F1
devices and a wired-OR connection of TERR signals from those same devices. This is
useful when several PSD813F1 devices are
“
chained
”
together in a JTAG environment.
9.6.3 Security and Flash Memories and EEPROM 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/verify commands are blocked. Full chip erase returns the part to a
non-secured blank state. The Security Bit can be set in PSDsoft Configuration.
All Flash Memory and EEPROM sectors can individually be sector protected against
erasures. The sector protect bits can be set in PSDsoft Configuration.
