Serial Peripheral Interface (SPI)
Data Length
Tx Data Buffer Pointer
7.12.5.6 SPI EVENT REGISTER (SPIE). The SPIE is an 8-bit register used to report events
recognized by the SPI and to generate interrupts. Upon recognition of an event, the SPI sets
its corresponding bit in the SPIE. Interrupts generated by this register may be masked in the
SPI mask register.
The SPIE is a memory-mapped register that may be read at any time. A bit is cleared by
writing a one (writing a zero does not affect a bit’s value). More than one bit may be cleared
at a time. All unmasked bits must be cleared before the CP will clear the internal interrupt
request. This register is cleared at reset.
.
Bits 7, 6, 3—Reserved
MME—Multi-Master Error
TXE—Tx Error
BSY—Busy Condition
TXB—Tx Buffer

The data length is the number of octets that the CP should transmit from this BD’s data
buffer. It is never modified by the CP. This value should normally be greater than zero.
If the number of data bits in the character is greater than 8, then the data length should
be even. Example: to transmit three characters of 8-bit data, 1 start, and 1 stop, the data
length field should be initialized to 3. However, to transmit three characters of 9-bit data,
the data length field should be initialized to 6 since the three 9-bit data fields occupy three
words in memory (the 9 LSBs of each word).
The transmit buffer pointer, which always points to the first location of the associated data
buffer, may be even or odd (unless the number of actual data bits in the character is great-
er than 8 bits, in which case the transmit buffer pointer must be even). The buffer may
reside in either internal or external memory.
The SPI detected that the SPISEL pin was asserted externally while the SPI was in master
mode.
An error occurred during transmission (underrun in SPI slave mode).
Received data has been discarded due to a lack of buffers. This bit is set after the first
character is received for which there is no receive buffer available.
A buffer has been transmitted. This bit is set once the transmit data of the last character
in the buffer was written to the transmit FIFO. The user must wait two character times to
be sure that the data was completely sent over the transmit pin.
