Table 30. JTAG Port Signals
9.6 Programming In-Circuit using the JTAG-ISP Interface
The JTAG-ISP interface on the PSD835G2 can be enabled on Port E (see Table 30). All
memory (Flash and Flash Boot Block), PLD logic, and PSD configuration bits may be
programmed through the JTAG-ISC interface. A blank part can be mounted on a printed
circuit board and programmed using JTAG-ISP.
The standard JTAG signals (IEEE 1149.1) are TMS, TCK, TDI, and TDO. Two additional
signals, TSTAT and TERR, are optional JTAG extensions used to speed up program and
erase operations.
*SR_cod and Periph Mode bits in the VM Register are always cleared to zero on power on or warm reset.

9.5.3.4 Reset of Flash Erase and Programming Cycles
An external reset on the RESET pin will also reset the internal Flash memory state
machine. When the Flash is in programming or erase mode, the RESET pin will terminate
the programming or erase operation and return the Flash back to read mode in tNLNH-A
(minimum 25 s) time.
By default, on a blank PSD (as shipped from factory or after erasure), four pins on Port E
are enabled for the basic JTAG signals TMS, TCK, TDI, and TDO.
See ST Application Note AN1153 for more details on JTAG In-System-Programming.
