The Busy Flag
When the busy flag is "1" it indicates that the S1D10605 Series chip is running internal processes, and at this time no
command aside from a status read will be received. The busy flag is outputted to D7 pin with the read instruction. If
t
the cycle time ( ) is maintained, it is not necessary to check for this flag before each command. This makes vast
CYC
improvements in MPU processing capabilities possible.
