Product Dependencies
23.6.1
I/O Lines
The pins used for interfacing the compliant external devices may be multiplexed with PIO lines.
The programmer must first program the PIO controllers to assign the SPI pins to their peripheral
functions. To use the local loopback function the SPI pins must be controlled by the SPI.
23.6.2
Power Management
The SPI clock is generated by the Power Manager. Before using the SPI, the programmer must
ensure that the SPI clock is enabled in the Power Manager.
In the SPI description, Master Clock (MCK) is the clock of the peripheral bus to which the SPI is
In the SPI description, Master Clock (MCK) is the clock of the peripheral bus to which the SPI is
connected.
23.6.3
Interrupt
The SPI interface has an interrupt line connected to the Interrupt Controller. Handling the SPI
interrupt requires programming the interrupt controller before configuring the SPI.
