7.3 Signal Format
The SIOP signal format is described here.
7.3.1 Serial Clock (SCK)
ThestateofSCKbetweentransmissionsmustbelogic1. Thefirstfalling
edge of SCK signals the beginning of a transmission. At this time, the
first bit of received data is accepted at the SDI pin and the first bit of
transmitted data is presented at the SDO pin. Data is captured at the
SDI pin on the rising edge of SCK. Subsequent falling edges shift the
data and accept or present the next bit. The transmission is ended upon
the eighth rising edge of SCK. The maximum frequency of SCK in slave
mode is equal to E (bus clock) divided by four. That is, for a 4-MHz
oscillator input, E becomes 2 MHz and the maximum SCK frequency is
0.5 MHz. There is no minimum SCK frequency.
In master mode, the format is identical except that the SCK pin is an
output and the shift clock now originates internally. The master mode
transmission frequency is fixed at E/4.
