Synchronous Serial Interface (SSI)
General Release Specification
SSI STATUS REG.
0 0 0 0 0 0
CLOCK GENERATOR
CONTROLS/ADDRESS BUS
Transmission in master mode is initiated by a write to the SSI data
register (SDR). A transfer cannot be initiated in slave mode; the external
master initiates the transfer. The programmer must choose between
master or slave mode before the SSI is enabled. The programmer must
ensure that only one master exists in the system at any one time. All
devices in the system must operate with the same clock polarity and
data rates. Slaves should always be disabled before the master is
disabled.
