Main Clock Input.
This input can be tied to GND. In this
case, the device is clocked by the internal
RC oscillator.
The Serial Fast Flash programming interface is based on IEEE Std. 1149.1 “Standard Test
Access Port and Boundary-Scan Architecture”. Refer to this standard for an explanation of
terms used in this chapter and for a description of the TAP controller states.
In this mode, data read/written from/to the embedded Flash of the device are transmitted
through the JTAG interface of the device.
In Serial Fast Flash Programming Mode, the device is in a specific test mode. Only a distinct
set of pins is significant. Other pins must be left unconnected.
