(8) Hold Timing
(VCC
= 5.0 V±10%, VSS = AVSS = 0.0 V, TA = 40 °C to +85 °C)
Note : More than 1 machine cycle is needed before HAK changes after HRQ pin is fetched.
(9) UART, Extended I/O Serial 0, 1 Timing
(VCC
= 5.0 V±10%, VSS = AVSS = 0.0 V, TA = 40 °C to +85 °C)
Notes: These are AC ratings in the CLK synchronous mode.
CL is the load capacitance value connected to pins while testing.
