TIMING WAVEFORM OF WRITE WITH
BUSY
NOTES:
1. tWH must be met for both
BUSY
input (slave) and output (master).
2.
BUSY
is asserted on port 'B' blocking R/
W
'B',
until
BUSY
'B'
goes High.
3. All timing is the same for left and right ports. Port 'A' may be either left or right port. Port 'B' is the opposite from port 'A'.
