NOTES: 7. Applies for external output buffers
8. These junction temperatures reflect simulated conditions. Absolute maximum junction temperature is 150°C. The customer is
responsible for verifying junction temperature.
9. These parameters apply for D7–D0, IRQ3–IRQ15, DRO0, DRO1, and DRO3.
10. These parameters apply for GPIO0–GPIO7, XSOUT, XRTS, XDTR, XIR–TXD.
11. These parameters apply for XOUT.
12. Measurement condition:
a) Normal operation other than sleep mode
VCC = 5 V, TA = 25°C.
Full duplex serial activity on all four serial (UART) channels at the clock frequency specified in above table with divisior of one.
b) Sleep mode
VCC = 5 V, TA = 25°C.
After enabling the sleep mode for all four channels, all serial and host activity is kept idle.
