(8) Ready Input Timing
(AVCC = VCC = 2.7 V to 5.5 V, AVSS = VSS = 0.0 V, TA = –40
°C to +85°C)
Note : Use the auto-ready function when the setup time for the rising of the RDY signal is not sufficient.
(9) Hold Timing
(AVCC = VCC = 2.7 V to 5.5 V, AVSS = VSS = 0.0 V, TA = –40
°C to +85°C)
* : For tCP (internal operating clock cycle time), refer to “(3) Clock Timing”.
Note : More than 1 machine cycle is needed before HAK changes after HRQ pin is fetched.
