Chapter 40: LPC43xx SPI
40.6.5 SPI Test Control Register
Note that the bits in this register are intended for functional verification only. This register
should not be used for normal operation.
40.6.6 SPI Test Status Register
Note:
The bits in this register are intended for functional verification only. This register
should not be used for normal operation.
This register is a replication of the SPI Status Register. The difference between the
registers is that a read of this register will not start the sequence of events required to
clear these status bits. A write to this register will set an interrupt if the write data for the
respective bit is a 1.
40.6.7 SPI Interrupt Register
This register contains the interrupt flag for the SPI0 interface.
