However, last operation from microprocessor read, ADNS-2610 will hold state SDIO until falling edge SCK. place SDIO into Hi-Z state, activate power-down mode writing configuration register.

Error Detection Recovery ADNS-2610 microcontroller might synchronization events, power supply droops microcontroller firmware flaws. ADNS-2610 transaction timer serial port. sixteenth rising edge spaced more than approximately milliseconds from first edge current transaction, serial port will reset. Invalid addresses: Writing invalid address will have effect. Reading from invalid address will return zeros. Collision detection SDIO only time that ADNS-2610 drives SDIO line during READ operation. avoid data collisions, microcontroller should relinquish SDIO before falling edge after last address bit. Then ADNS-2610 begins drive SDIO after next rising edge SCK. Next, ADNS-2610 relinquishes SDIO within falling edge after last data bit. microcontroller begin driving SDIO time after that. order maintain power consumption normal operation when
high, microcontroller should leave SDIO floating until next transmission (although that will cause communication difficulties). case synchronization failure, both ADNS-2610 microcontroller drive SDIO. ADNS-2610 withstand short circuit current will withstand infinite duration short circuit conditions. microcontroller verify successful write operation issuing read command same address comparing written data read data. microcontroller verify synchronization serial port periodically reading product from status register (Address: 0x01). Notes Power-up Serial Port sequence which VDD, SDIO during powerup affect operation serial port. diagram below shows what happen shortly after powerup when microprocessor tries read data from serial port. This diagram shows rising valid levels, some point microcontroller starts

Then, microcontroller waits ensure ADNS-2610 powered ready communicate. microprocessor then tries read from location 0x01, Status register, expecting value 0x0b000XXXXX where DON'T CARE state. receives this value, then knows that communication ADNS-2610 operational. problem occurs ADNS-2610 powers before microprocessor sets SDIO lines outputs high. ADNS-2610 sees raising valid rising edge, clocks state SDIO first address (sets either read write depending upon state). case SDIO low, read operation will start. When microprocessor actually begins send address, ADNS-2610 already first address. When seventh sent microprocessor, ADNS-2610 valid address, drives SDIO line high within (see detail Figure Figure 22). This results fight SDIO. Since address wrong, data sent back will incorrect. case SDIO high, write operation will start. address data will synchronization, causing wrong data written wrong address.
