7.6 SPI Test Status Register (SPTSR - 0xE002 0014)
7.7 SPI Interrupt Register (S0SPINT - 0xE002 001C)
Table 466: SPI Test Control Register (SPTCR - address 0xE002 0010) bit description
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.
Table 467: SPI Test Status Register (SPTSR - address 0xE002 0014) bit description
This register contains the interrupt flag for the SPI0 interface.

SPI interrupt flag. Set by the SPI interface to generate an interrupt. Cleared
by writing a 1 to this bit.
Note: this bit will be set once when SPIE = 1 and at least one of SPIF and
WCOL bits is 1. However, only when the SPI Interrupt bit is set and SPI0
Interrupt is enabled in the VIC, SPI based interrupt can be processed by
interrupt handling software.
Reserved, user software should not write ones to reserved bits. The value
read from a reserved bit is not defined.
Description
Reserved, user software should not write ones to reserved bits.
The value read from a reserved bit is not defined.
SPI test mode. When 0, the SPI operates normally. When 1,
SCK will always be on, independent of master mode select, and
data availability setting.
Description
Reserved, user software should not write ones to reserved bits.
The value read from a reserved bit is not defined.
Slave abort.
Mode fault.
Read overrun.
Write collision.
SPI transfer complete flag.
