Dual interface serial bus |
摘要 |
<p>An electronic device (400) includes a dual interface serial bus that can support either the I2C or SPI serial interfaces. The device (400) defaults using the I2C serial interface for the transmission and reception of data. However, when the CE line (406) transitions from a logic high to a logic low state, the device (400) automatically reprograms the I/O to support the SPI interface standard. Both interfaces are supported without the use of an additional interface selection pin (308). <IMAGE></p> |
