46NOTES
47=====
48
49(1) Only stub console driver available at the moment.
50    Driver for the on-chip serial devices (sci) will be available soon.
51
52(2) The present 'hw_init.c' file is incomplete and does not set all
53    registers required for serial I/O. The effect is that the sci devices
54    are 'muted' and do not successfully transmit characters to the respective
55    I/O lines on the SH7045F.  If these ports have been properly initialized,
56    they are not disabled by the current code. A two-part initialization will
57    be available soon.
