94 / 113 page  MB90480/485 Series 94 (8) Hold Timing (VCC = 2.7 V to 3.6 V, VSS = 0.0 V, TA = 0 °C to +70 °C) * : tCP : See “ (1) Clock Timing Standards”. Note : One or more cycles are required from the time the HRQ pin is read until the HAK signal changes. (9) UART Timing (VCC = 2.7 V to 3.6 V, VSS = 0.0 V, TA = −40 °C to +85 °C) *1 : CL is the load capacitance applied to pins for testing. *2 : tCP : See “ (1) Clock Timing Standards”. Note : AC ratings are for CLK synchronized mode.
