Serial Peripheral Interface (SPI)
Signal Descriptions
MC9S12DP256 — Revision 1.1
Serial Peripheral Interface (SPI)
SCK port output
enable (sck_obe)
This pin indicates that the SCK output buffer is enabled if sck_port_en
was set.
Output Signals
Master Data out
(spi_mosi_do)
This pin is used to transmit data out of the SPI module when it is
configured as a Master.
Slave Data out
(spi_miso_do)
This pin is used to transmit data out of the SPI module when it is
configured as a Slave.
Slave select out
(spi_ss_do)
This pin is used to output the select signal from the SPI module to
another peripheral with which a data transfer is to take place.
Serial Clock out
(spi_sck_do)
This pin is used to output the clock with respect to which the SPI
transfers data.
