• Manufacturer Part Number: peb20534
• Description: Dma Supported Serial Communication Controller With 4 Channels
• Manufacturer: Infineon Technologies Corporation

Note: The transmit interrupt notifies the CPU about the start of a transmission.
Example
To check for transmit errors only:
SSCIM(bit 1)=‘1‘, SSCCON(bit 8)=‘1‘, SSCCON(bit 10)=‘0‘,SSCCON(bit 11)=‘0‘
Data Sheet
IMRX
IMER
IMTX
The receive interrupt notifies transfer of the received data to the shared memory.
The error interrupt notifies the CPU about different error conditions related to data
transmission and reception. To further specify what sort of error interrupt the user
wants to trace, the corresponding bits of the SSC control register SSCCON has to
be set. The SSC error conditions that can be checked are transmit errors
(SSCCON(bit 8) =‘1‘), phase errors (SSCCON(bit 10)=‘1‘) and baud rate errors
(SSCCON(bit 11)=‘1‘). If any of these error conditions shall not be checked, the
corresponding enable bit has to be set to ‘0‘.
