• Manufacturer Part Number: sak-xc888clm-8ffa
• Description: High Performance 8-bit Microcontroller With On-chip Flash Memory And Can
• Manufacturer: Infineon Technologies Corporation

Data is transmitted or received on lines TXD and RXD, which are normally connected to
the pins MTSR (Master Transmit/Slave Receive) and MRST (Master Receive/Slave
Transmit). The clock signal is output via line MS_CLK (Master Serial Shift Clock) or input
via line SS_CLK (Slave Serial Shift Clock). Both lines are normally connected to the pin
SCLK. Transmission and reception of data are double-buffered.
