Frequently asked questions

What silicon revision does this anomaly list apply to?

The anomalies listed apply to all ADuC7023 packaged material branded as Revision A silicon.

What is the workaround for the SPI bit rate issue?

Set the SPIDIV register to a value less than or equal to 0x32, or set SPICON[6] = 1 to initiate transfers on a write to SPITX.

How can the I2C slave interface be disabled safely?

First enable master mode by setting I2CxMCON Bit 0 = 1, then disable slave mode by clearing I2CxSCON Bit 0, and finally clear I2CxMCON Bit 0.
