PIN DESCRIPTION
2.2.11 MISCELLANEOUS
SPKRD Speaker Drive. This the output to the
speaker and is AND of the counter 2 output with
bit 1 of Port 61, and drives an external speaker
driver. This output should be connected to 7407
type high voltage driver.
SCL, SDA I C Interface . These bidirectional pins
are connected to CRTC register 3Fh to implement

DDC capabilities. They conform to I
specifications, they have open-collector output
drivers which are internally connected to V
through pull-up resistors.
They can be used for the DDC1 (SCL) and DDC0
(SDA) lines of the VGA interface.
