(8) Ready Input Timing
(AVCC = VCC = 5.0 V
±10%, AVSS = VSS = 0.0 V, TA = –40°C to +85°C)
Note: Use the automatic ready function when the setup time for the rising edge of the RDY signal is not sufficient.
(9) Hold Timing
(AVCC = VCC = 5.0 V
±10%, AVSS = VSS = 0.0 V, TA = –40°C to +85°C)
* : For tCP (internal operating clock cycle time), refer to “(3) Clock Timings.”
Note: More than 1 machine cycle is needed before HAK changes after HRQ pin is fetched.
