Single and continuous transmission signal sequences for Motorola SPI format with SPO=1,
SPH=0 are shown in
In this configuration, during idle periods
SCLKIN

SSPTXD
Note: In
SSPOE
• the SCLKOUT signal is forced HIGH
• SFRMOUT is forced HIGH
• the transmit data line SSPTXD is arbitrarily forced LOW
• when the SSP is configured as a master, the SSPCTLOE line is driven LOW, enabling
• when the SSP is configured as a slave, the SSPCTLOE line is driven HIGH, disabling
