the capability to toggle power (Vddd, Vdda, All Vddio’s) to PSoC 5. This may typically require
external interface circuitry to toggle power which will depend on the programming setup. The power
supplies can be brought up in any sequence, however, once stable, VDDA must be greater than or
equal to all other supplies.
using external pull-down resistor (around 100 K resistor). This is required for P15[7] SWDCK signal to be seen by
PSoC 5's internal logic.
Vdda must be greater than or equal to all other power supplies (Vddd, Vddio’s) in PSoC 5.
For Power cycle mode Programming, XRES pin is not required. But the Host programmer must have
When USB SWD pins are used for Programming, the P1[1] SWDCK pin must be externally connected to Ground
