Ready/Busy Status
During the internal write operation the S93662/663 memory array is inaccessible. After starting the write operation
(taking CS low) the host can implement a 10ms time-out routine or alternatively it can employ a polling routine that tests
the state of the DO pin.
After starting the write, testing for the status is easily accomplished by taking CS high and testing the state of DO. If
it is low the device is still busy with the internal write. If it is high the write operation has completed.
For the polling routine the host has the option of toggling CS for each test of DO, or it can place CS high and then
intermittently test DO. SK is not required for any of these operations. Once the device is ready, it will continue to drive
DO high whenever the S93662/663 is selected. The ready state of DO can be cleared by clocking in a start bit; this
start bit can either be the beginning of a new command sequence or it can be a dummy start bit with CS returning low
before the host issues a new command.
