I'm designing a main PCB board for one aplication with the uPSD3312D-40T6, in this proyect I need to control external circuits like TPICS6259 and OUTPUT like 74HC573, these kind of integrates need a Reset signal, is possible to obtein a external reset with the uPSD3312D-40T6 to can reset this external devices, when a reset happens ?

Sorry for my english.

Yes, you can use one of the port pins such as PB.0 then in the PSDsoft Express Pin Definitions menu set this port pin to ''Combinatorial'' under the ''CPLD Output'', then in the I/O Logic equation menu set this pin to equal to _reset. This way you should be getting a reset output every time when receive a _reset input to the uPSD.
