Bit 1 – USICLK: Clock Strobe

Writing a one to this bit location strobes the Shift Register to shift one step and the counter to increment by one,

provided that the USICS1...0 bits are set to zero and by doing so the software clock strobe option is selected. The

output will change immediately when the clock strobe is executed, i.e., in the same instruction cycle. The value

shifted into the Shift Register is sampled the previous instruction cycle. The bit will be read as zero.

When an external clock source is selected (USICS1 = 1), the USICLK function is changed from a clock strobe to a

Clock Select Register. Setting the USICLK bit in this case will select the USITC strobe bit as clock source for the 4-

Bit 0 – USITC: Toggle Clock Port Pin

Writing a one to this bit location toggles the USCK/SCL value either from 0 to 1, or from 1 to 0. The toggling is inde-

pendent of the setting in the Data Direction Register, but if the PORT value is to be shown on the pin the DDRE4

must be set as output (to one). This feature allows easy clock generation when implementing master devices. The

bit will be read as zero.

When an external clock source is selected (USICS1 = 1) and the USICLK bit is set to one, writing to the USITC

strobe bit will directly clock the 4-bit counter. This allows an early detection of when the transfer is done when oper-

ating as a master device.
