33.8 Core and Bus Independent Clocks for Peripherals
The following table lists the peripherals that can operate while the core, bus and peripheral clock frequencies are modified, thus providing communications at a bit rate which is independent for the core/bus/peripheral clock. This mode of operation is possible by using the internally generated independent clock sources.
Peripheral | Specific Clock Requirements |
---|---|
GMAC | – |
UDPHS | – |
UHPHS | – |
CLASSD | GCLK |
I2SC | GCLK |
FLEXCOM (USART, SPI, TWI) | GCLK |
ISC | PCK (pad clock) |
MCAN | GCLK |
TC | GCLK |
ADC | GCLK |
UART | GCLK |
TWI | GCLK |
SPI | GCLK |
