32.3.4 Interrupt Requirements
The SPI interface generates interrupts.
ECSPI interrupt requirements are listed in table below.

The typical values are based on a baud rate of 1 Mbps with a receiver trigger level (Rxtl)
of 1 and a 32-bit transfer length. The worst-case is based on a baud rate of 12 Mbps (max
supported by the SPI interface) with a 8-bits transfer length.
