• Manufacturer Part Number: SAA-XC866-1FRA
• Description: 8-Bit Single-Chip Microcontroller
• Manufacturer: INFINEON [Infineon Technologies AG]

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.
