1. The current absorbed by the chip IIO must always follow the absolute maximum ratings

given in the table, and the sum of IIO (all I/O feet and control pins) must not exceed

IVSS.

2. The current output IIO of the chip must always follow the absolute maximum rating

given in the table, and the sum of IIO (all I/O pins and control pins) must not exceed

IVDD.

3. Data based on characterization results. Not tested in production.

Input/output AC characteristics

The definitions and values of the input and output AC characteristics are given in figure 18

and Table 32, respectively.

Unless otherwise stated, the parameters listed in Table 32 are measured using the ambient

temperature and supply voltage in accordance with the condition Table 7.
