7.7.9.
Bus hold timing
(VDD35 = 4.5 V to 5.5 V, Vss5 = AVss5 = 0 V, TA =
40 °C to + 125 °C)
Note : BRQ must be kept High until the bus is granted (this is acknowledged by the falling edge of BGRNTX).
It must be kept High as long as the bus shall be hold.
After releasing the bus (BRQ set to Low) this is acknowledged by the rising edge of BGRNTX.
