FUNCTIONAL DEVICE OPERATION
OPERATIONAL MODES
SERIAL PERIPHERAL INTERFACE
The serial peripheral interface (SPI) creates the
communication link between the microcontroller and the
908E626.
The interface consists of four pins (see Figure 11):
SS—Slave Select
MOSI—Master-Out Slave-In
MISO—Master-In Slave-Out
SPSCK—Serial Clock (maximum frequency 4.0 MHz)
A complete data transfer via the SPI consists of 2 bytes.
The master sends address and data, slave system status,
and data of the selected address.
Figure 11. SPI Protocol
During the inactive phase of SS, the new data transfer is
prepared. The falling edge on the SS line indicates the start
of a new data transfer and puts MISO in the low-impedance
mode. The first valid data are moved to MISO with the rising
edge of SPSCK.
The MISO output changes data on a rising edge of
SPSCK. The MOSI input is sampled on a falling edge of
SPSCK. The data transfer is only valid if exactly 16 sample
clock edges are present in the active phase of SS.
After a write operation, the transmitted data is latched into
the register by the rising edge of SS. Register read data is
internally latched into the SPI at the time when the parity bit
is transferred. SS HIGH forces MISO to high-impedance.
MASTER ADDRESS BYTE
A4:A0
Contains the address of the desired register.
R/W
Contains information about a read or a write operation.
If R/W = 1, the second byte of master contains no valid
information, slave just transmits back register data.
If R/W = 0, the master sends data to be written in the
second byte, slave sends concurrently contents of
selected register prior to write operation, write data is
latched in the SMARTMOS register on rising edge of
SS
.
Parity P
The parity bit is equal to “0” if the number of 1 bits is an
even number contained within R/W, A4:A0. If the number of
1 bits is odd, P equals “1”. For example, if R/W = 1, A4:A0 =
00001, then P equals “0.”
The parity bit is only evaluated during a write operation.
Bit X
Not used.
Master Data Byte
Contains data to be written or no valid data during a read
operation.
