(6) Timing Requirements
Table 20 Timing requirements (1)
(VCC = 4.0 to 5.5 V, VSS = 0 V, Ta =
20 to 85 °C, unless otherwise noted)
NOTES:
1. As for CAP0, it is the value when noise filter is not used.
2. In this time, bit 6 of the serial I/O control register (address 001A16) is set to “1” (clock synchronous serial I/O is selected).
When bit 6 of the serial I/O control register is “0” (clock asynchronous serial I/O is selected), the rating values are divided by 4.
