Figure 1.69. Vbus detect interrupt timing
Rev.2.00
REJ03B0005-0200
To avoid receiving a false Vbus detect interrupt at start-up, the Vbus detect should be enabled before enabling the Vbus
detect interrupt. Use the following procedure when enabling the Vbus detect function:
1) Enable Vbus detect by setting the Vbus detect enable bit to "1" (bit 7 at address 001F
2) Clear the Vbus detect interrupt by setting the Vbus detect interrupt request bit to "0" (bit 3 at address 005C
3) Enable the Vbus detect interrupt by setting the Vbus detect interrupt priority level greater than "000" (bits 2-0 at
address 005C
Figure 1.69 shows the Vbus detect interrupt timing

Note 1: Maximum time from Vbus detection to when interrupt request bit is set is 1ms.
Note 2: Maximum time from when setting Vbus detect enable bit to "1" to when interrupt requeset bit is set is 500us.
Note 3. VbusDTCT guaranteed minimum pulse width accepted is 50us.
