(VCC = 1.8 to 5.5 V, VSS = 0 V, Ta =
20 to 85 °C, unless otherwise noted)
NOTES:
1. P20 and P21 indicates these pins are used as I/O ports.
2. XIN and XCIN indicates these pins are used as clock pins.
3. P05 is measured when the P05/TXD P-channel output disable bit of the UART control register (bit 4 of address 001B16) is “0”.
4. It is available only when operating key-on wake up.
