This option selects the operating frequency of the XTAL (crystal) clock used to drive the ESP target.
|
|
The selected value MUST reflect the frequency of the given hardware.
|
|
|
|
Note: ESP32C5 supports crystal frequencies of 40 MHz and 48 MHz. With XTAL_FREQ_AUTO option, boot
|
|
mode together with MTMS pin, EFUSE_XTAL_48M_SEL, and EFUSE_XTAL_48M_SEL_MODE collectively control
|
|
the crystal frequency, and record to PCR_CLK_XTAL_FREQ register field.
