Synchronous check register (SYNCK)
Addr=23h; reset value=E4h
Read-only
Table 32.
This register contains a fixed code (E4h) that can be read to check the synchronization of
the MCU interface.
DSP status register (CTRLACK)
Addr=25h; reset value=01h
Read-only
Table 33.
CKEND bit is 0 while the checksum calculation is performed: in the other time is always set
to 1.
INIT bit becomes active (INIT = 1) after the DSP initialization. Normally it requires 70 µs
after the reset to be set to 1.
Checksum register (CKSUM)
Addr=26h; reset value=00h
Addr=27h; reset value=00h
Read-only
