6.3.19

Delay block (DLYB) characteristics

Unless otherwise specified, the parameters given in Table 85 for the delay block are derived

from tests performed under the ambient temperature, frcc_c_ck frequency and VDD supply

voltage summarized in Table 22: General operating conditions.

6.3.20

16-bit ADC characteristics

Unless otherwise specified, the parameters given in Table 85 are derived from tests

performed under the ambient temperature, fPCLK2 frequency and VDDA supply voltage

conditions summarized in Table 22: General operating conditions.
