SPI Active Mode
The waveform shows the perspective from the control block without any optional
external pull-up or pull-down resistors connected.
| Symbol | Parameter | Frequency | Min | Typ | Max | Units |
|---|---|---|---|---|---|---|
| fMAX_M | Active mode internal configuration clock frequency. | DIV1 | 52 | 80 | 100 | MHz |
| DIV2 | 26 | 40 | 52 | MHz | ||
| DIV4 | 13 | 20 | 26 | MHz | ||
| DIV8 | 6.5 | 10 | 13 | MHz | ||
| fMAX_M_EXTCLK | Active mode external configuration clock frequency. | – | – | – | 100 | MHz |
| tSU | Setup time. Test condition at 1.8 V I/O standard and 0 pF output loading. | – | – | – | ns | |
| tH | Hold time. Test condition at 1.8 V I/O standard and 0 pF output loading. | – | 0 | – | – | ns |
| tDMIN | Minimum time between deassertion of CRESET_N to first valid configuration data. | – | 32 | – | – | μs |
Important: The JTAG pins must be inactive during SPI active configuration.
The
EXT_CONFIG_CLK pin must be inactive during SPI active
configuration if the internal oscillator is selected as the configuration clock
source (default).
