PNX1300/01/02/11 Data Book
A detailed description of the configuration of the receiver
can be found in the SSI_CTL and SSI_CSR register de-
scription
SSI_RxDR is a 32-bit MMIO receive data register.
Due to the possibility of speculative reading of the
SSI_RxDR, the read itself can not be implemented to ac-
knowledge the data as a side effect. For this reason an
explicit acknowledge mechanism is provided by the
SSI_RxACK register.
The SSI_RxACK is a 1-bit MMIO register that is used to
signal the SSI receiver state machine that a word has
been successfully read from the SSI_RxDR.

Writing a ‘1’ to this register initiates updating of the inter-
nal state. Writing a ‘0’ has no effect.
The register cannot be read, its effect may be observed
in the WAR field of the SSI_CSR.
The status fields of the SSI_CSR will update within 1
highway clock cycle after writing to the SSI_RXACK reg-
ister.
