3.1 Electrical characteristics
When STP instruction
is executed with clock
stopped, output
transistors isolated.
Note 1: P45 is measured when the P45/TXD P-channel output disable bit of the UART control register (bit 4 of address 001B16) is “0”.
P51 is measured when the P51/SOUT2 P-channel output disable bit of the serial I/O2 control register (bit 7 of address 001D16) is “0”.
2: With output transistors isolated and A-D converter having completed conversion, and not including current flowing through VREF pin.
