MOTOROLA
Serial Peripheral Interface Modules (SPI 1 and SPI 2)
18.3.5 Test Registers
The SPI test registers allow the user to internally connect the receive and transmit sections, display the
status of the state machine, and monitor the contents of the receive and transmit FIFOs.

Name
Description
Settings
Reserved
Bits 31–15
Reserved—These bits are reserved and should read 0.
LBC
Bit 14
Loop Back Control
—Internally connects the receive and
transmit sections internally for test purposes.
0 = RX and TX sections are not
internally connected
1 = RX and TX sections are
internally connected
Reserved
Bits 13–12
Reserved—These bits are reserved and should read 0.
SSTATUS
Bits 11–8
State Machine Status
—Indicates the state machine status (used for test purposes only).
RXCNT
Bits 7–4
RXFIFO Counter
—Indicates the number of data words in the
RXFIFO.
0000 = RXFIFO is empty
0001 = 1 data word in RXFIFO
0010 = 2 data words in RXFIFO
0011 = 3 data words in RXFIFO
0100 = 4 data words in RXFIFO
0101 = 5 data words in RXFIFO
0110 = 6 data words in RXFIFO
0111 = 7 data words in RXFIFO
1000 = 8 data words in RXFIFO
