Section 23 Serial Protocol Interface (HSPI)
23.5
Power Saving and Clocking Strategy
The HSPI operates synchronized with the bus clock.
Module standby mode can be enabled or disabled by controlling the CSTP22 bit in the clock stop
register (CLKSTP00) in the CPG module.
To power down the module, follow the following procedure.
1. Ensure all data transfers have taken place. That is, the transmit buffer (or FIFOs) should be
empty and the receive buffer (or FIFOs) should have been read until they are empty.
2. Disable all DMA requests and interrupt requests. Disable FIFO mode.
3. Set the CSTP22 bit in clock stop clear register (CLKSTP00) to 1.
To wake up the HSPI, the CSTP22 bit in the clock stop register (CLKSTPCLR00) should be set to
1.
