USI Module

Function

SPI master generates one additional clock after module reset Bug

Description

Initalizing the USI in SPI MASTER mode with the USICKPH bit set generates one additional clock pulse than defined by the value in the USICNTx bits on the SCLK pin during the first data transfer after module reset. For example, if the USICNTx bits hold the value eight, nine clock pulses are generated on the SCLK pin for the first transfer only.

Workaround

Load USICNTx with a count of N-1 bits (where N is the required number of bits) for the first transfer only.
