Register Descriptions
This section describes the registers of the Geode CS9210
graphics companion. The internal register map is shown
in Table 4-1, followed by descriptions of the individual reg-
isters and their bit formats. All registers are accessed
through the serial interface, one byte at a time.
Note:
All reserved bits must be written to 0 unless oth-
erwise specified.
