Under development Preliminary specification

Specifications in this manual are tentative and subject to change.

Table 5.8

Electrical Characteristics (3/3) (VCC1 = VCC2 = 5.5 V, VSS = 0 V, Topr = 25

°C)

NOTES:

1. In single-chip mode, leave the output pins open and connect the input pins to VSS.

2. When setting the FMSTP bit in the FMR0 register to 1 (flash memory stopped) and running the program on

RAM.

3. When the FMR40 bit in the FMR4 register is set to 1 (low-speed access).

4. When the FMR40 bit is set to 1 and the MRS bit in the VRCR register is set to 1 (main voltage regulator stops).

5. When the MRS bit is set to 1.

6. When the MRS bit is set to 1 and the CM0 bit in the CM03 register is set to 0 (XCIN-XCOUT drive capability

Low).
