19.3.2.11 eQADC CFIFO Status Register (EQADC_CFSR)
The EQADC_CFSR contains the current CFIFO status. The EQADC_CFSRs are read only. Writing to the
EQADC_CFSR has no effect.
17–20
LCFTSSI
[0:3]
Last CFIFO to transfer commands through the eQADC SSI. Holds the CFIFO number of last CFIFO to have
initiated a command transfer to an external command buffer through the eQADC SSI. LCFTSSI does not
indicate the transmission of null messages. LCFTSSI has the following values:
21–31
TC_LCFTSSI
[0:10]
Transfer counter for last CFIFO to transfer commands through eQADC SSI. Indicates the number of commands
which have been completely transferred from a particular CFIFO at the time a command transfer from that
CFIFO to an external command buffer is initiated. TC_LCFTSSI is a copy of the corresponding TC_CF
n in
EQADC_CFTCRn (see Section 19.3.2.9, “eQADC CFIFO Transfer Counter Registers 0–5 (EQADC_CFTCRn) ”)
captured at the time a command transfer to an external command buffer is initiated. This field has no meaning
when LCFTSSI is 0b1111.
