LPC2930
ARM9 microcontroller with CAN, LIN, and USB
The SPI module’s operating mode, frame format, and word size are programmed through
the SLVn_SETTINGS registers.
A single combined interrupt request SPI_INTREQ output is asserted if any of the
interrupts are asserted and unmasked.
Depending on the operating mode selected, the SPI SCS outputs operate as an
active-HIGH frame synchronization output for Texas Instruments synchronous serial
frame format or an active-LOW chip select for SPI.
Each data frame is between four and 16 bits long, depending on the size of words
programmed, and is transmitted starting with the MSB.

Pin description
The SPI pins are combined with other functions on the port pins of the LPC2930, see
Section 6.10.3
.
Table 17
shows the SPI pins (x runs from 0 to 2; y runs from 0 to 3).

[1]
Direction of SPIx SCS and SPIx SCK pins depends on master or slave mode. These pins are output in
master mode, input in slave mode.
[2]
In slave mode there is only one chip select input pin, SPIx SCS0. The other chip selects have no function in
slave mode.
6.11.5.3
Clock description
The SPI modules are clocked by two different clocks; CLK_SYS_PESS and CLK_SPIx
(x = 0, 1, 2), see
Section 6.6.2
. Note that each SPI has its own CLK_SPIx branch clock for
power management. The frequency of all clocks CLK_SPIx is identical as they are derived
from the same base clock BASE_CLK_SPI. The register interface towards the system bus
is clocked by CLK_SYS_PESS. The serial-clock rate divisor is clocked by CLK_SPIx.
The SPI clock frequency can be controlled by the CGU. In master mode the SPI clock
frequency (CLK_SPIx) must be set to at least twice the SPI serial clock rate on the
interface. In slave mode CLK_SPIx must be set to four times the SPI serial clock rate on
the interface.
6.11.6
General-purpose I/O
The LPC2930 contains six general-purpose I/O ports located at different peripheral base
addresses. In the 208-pin package all six ports are available. All I/O pins are bidirectional,
and the direction can be programmed individually. The I/O pad behavior depends on the
configuration programmed in the port function-select registers.
The key features are:
General-purpose parallel inputs and outputs.
Direction control of individual bits.
Synchronized input sampling for stable input-data values.
