JTAG
The JTAG function is installed in this LSI.
Note that the terminal INITXI should be input in "L" when using JTAG.
Notes when quartz vibrator is mounted
The crystal oscillation circuit built into this LSI operates by the following compositions.
OSCC
Pin description
Pin name
OSCC
OSCEA
OSCEB
When OSCCL is input, the OSCEA and OSCEB oscillate at the natural frequency of the crystal oscillator and
propagated into the LSI.
