Status register 1 indicates the status of serial communications, results from ID checks and results from
check sum comparisons. It can be read after the SRD by writing the read status register command (70
Also, status register 1 is cleared by writing the clear status register command (50

This flag indicates whether the control program was downloaded to the RAM or not, using the down-
load function.
This flag indicates whether the check sum matches or not when a program, is downloaded for execu-
tion using the download function.
These flags indicate the result of ID checks. Some commands cannot be accepted without an ID
check.
This flag indicates when a time out error is generated during data reception. If this flag is attached
during data reception, the received data is discarded and the microcomputer returns to the command
wait state.
