Parallel synchronous slave interface (PSSI) characteristics
Unless otherwise specified, the parameters given in Table 99 and Table 100 for PSSI are
derived from tests performed under the ambient temperature, fHCLK frequency and VDD
supply voltage summarized in Table 12: General operating conditions.
