I/O Lines
Power Management
Interrupt
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.
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
connected.
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.
