Static Memory Controller (SMC)
Serial Synchronous Controller (SSC)
SMC: SMC Delay Access
SSC: Data sent without any frame synchro
SSC: Unexpected delay on TD output
In this document, the Access is “Read-write” in the Register Mapping Table (SMC_DELAY1 to
SMC_DELAY8 rows), and in the SMC DELAY I/O Register.
The current access is “Write-only”.
None
When SSC is configured with the following conditions:
The data is sent but there is not any toggle of the TF line
Transmit STTDLY must be different from 0.
When SSC is configured with the following conditions:
Unexpected delay of 2 or 3 system clock cycles is added to TD output.
None
• RF is in input,
• TD is synchronized on a receive START (any condition: START field = 2 to 7)
• TF toggles at each start of data transfer
• Transmit STTDLY = 0
• Check TD and TF after a receive START,
• TCMR.STTDLY more than 0
• RCMR.START = Start on falling edge/Start on Rising edge/Start on any edge
• RFMR.FSOS = None (input)
• TCMR.START = Receive Start
