R00–R03: Output port data (0F3H)
Sets the output data for the output ports.
When "1" is written: High output
When "0" is written: Low output
Reading: Valid
The output port terminals output the data written to the corresponding registers (R00–R03) without
changing it. When "1" is written to the register, the output port terminal goes high (VDD), and when "0" is
written, the output port terminal goes low (VSS).
At initial reset, these registers are all set to "1".
R00 (when FOUT is selected): Special output control (0F3H D0)
Controls the FOUT (clock) output.
When "1" is written: High level (DC) output
When "0" is written: Clock output
Reading: Valid
When "0" is written to the FOUT (R00) register, the FOUT (R00) terminal outputs the FOUT signal.
At initial reset, this register is set to "1".
XFOUT0, XFOUT1: FOUT frequency control (0FDH D0 and D1)
Selects the output frequency when the R00 port is set for FOUT output.
