SR03
read/write at I/O address 3C5h with index at address 3C4h set to 03h
Note: In text modes, bit 3 of the video data’s attribute byte normally controls the foreground intensity. This
bit may be redefined to control switching between character sets. This latter function is enabled whenever
there is a difference in the values of the Character Font Select A and the Character Font Select B bits. If
the two values are the same, the character select function is disabled and attribute bit 3 controls the
foreground intensity.

Character Map Select Bits for Character Map A
These three bits are used to select the character map (character generator tables) to be used as
the secondary character set (font). Note that the numbering of the maps is not sequential.
Character Map Select Bits for Character Map B
These three bits are used to select the character map (character generator tables) to be used as
the primary character set (font). Note that the numbering of the maps is not sequential.
Bit 1 of the Memory Mode Register (SR04) must be set to 1 for the character font select function of
this register to be active. Otherwise, only character maps 0 and 4 are available.
