M68HC11 K Series
MC68HC11KTS/D
8 Serial Peripheral Interface
The SPI allows the MCU to communicate synchronously with peripheral devices and other micropro-
cessors. Data rates can be as high as 2 Mbits per second when configured as a master and 4 Mbits per
second when configured as a slave (assuming 4 MHz bus speed).
Two control bits in OPT2 allow the transfer of data either MSB or LSB first and select an additional divide
by four stage to be inserted before the SPI baud rate clock divider.
