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 kΩ pull-up resistors to VCC on all JTAG-

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.
