5.3.2

Operating conditions at power-up/power-down

The parameters given in the table below are derived from tests performed under the

ambient temperature condition summarized in Table 33.

5.3.3

Embedded reset and power control block characteristics

The parameters given in the table below are derived from tests performed under the

ambient temperature conditions summarized in Table 33.

6. The I/Os powered by VSW are:

- PC13, PC14, PC15 when VDD is present.

- PC13, PC14, PC15, and all FT_t I/Os in VBAT mode.

7. In low-power dissipation state, TA can be extended to this range as long as TJ does not exceed TJ max.
