qStatus Register 1 (SRD1)
The status register 1 indicates the status of serial communica-
tions, results from ID checks and results from check sum
comparisons. It can be read after the SRD by writing the read sta-
tus register command (7016). Also, status register 1 is cleared by
writing the clear status register command (5016).
Table 17 lists the definition of each status register 1 bit. At power-
on, when user ROM area is blank, this register becomes “0C16”,
and when writing to the area is completed, the register becomes
“0016”, and the flag status is maintained even after the reset.

Status name
Boot update completed bit (SR15)
This flag indicates whether the control program was downloaded
to the RAM or not, using the download function.
Check sum consistency bit (SR12)
This flag indicates whether the check sum matches or not when a
program, is downloaded for execution using the download func-
tion.
ID check completed bits (SR11 and SR10)
These flags indicate the result of ID checks. Some commands
cannot be accepted without an ID check.
Data reception time out (SR9)
This flag indicates when a time out error is generated during data
reception. If this flag is attached during data reception, the re-
ceived data is discarded and the MCU returns to the command
wait state.
