They are: change path of TX2UL. The entries of the six operations modes (20-pin CSP package has 5 operation modes) are listed in ■ Normal Operation Mode Table 4 and Table 5. There are three mode change transactions ■ Configuration Mode that require the RESET_N assert or deassert with tSTATE (see Table 21

CY7C68003 The operation and configuration modes are described in Sleep Mode Operation Modes on page 4 and Configuration Mode on page 14 Sleep mode is entered by asserting RESET_N during the Normal respectively. The ULPI Low power mode and Sleep mode are Operation Mode. When RESET_N is driven low for tSTATE (see described in the following sections: Table 21 on page 19 for tSTATE requirement) while CS_N is low, TX2UL enters into Sleep Mode. VCC must remain supplied (ON) ULPI Low Power Mode during
