from multiple DSM2190F4V devices and a wired-
OR connection of TERR signals from those same
devices. This is useful when several devices are
“chained” together in a JTAG environment. PSD-
soft Express puts TSTAT and TERR signals to
open-drain by default. Click on 'Properties' in the
JTAG-ISP window of PSDsoft Express to change
to standard CMOS push-pull. It is recommended
to use 10 k
ISP signals on your circuit board.

Initial Delivery State
When delivered from ST, the device has all bits in
the memory and PLDs erased to logic 1. The DSM
Configuration Register bits are set to 0. The code,
configuration, and PLD logic are loaded using the
programming procedure. The four basic JTAG ISP
signals (TCK, TMS, TDI, TDO) are ready for ISP
function.
