• Apply GND, VDDIO, VDDCORE, VDDFLASH and VDDPLL.
• Apply XIN clock within T
• Wait for T
• Reset the TAP controller clocking 5 TCK pulses with TMS set.

Idle state.
Test-Idle state.
Idle state.
After reset, the device is clocked by the internal RC oscillator. Before clearing RDY signal, if an
external clock (> 32 kHz) is connected to XIN, then the device will switch on the external clock.
Else, XIN input is not considered. An higher frequency on XIN speeds up the programmer
handshake.
