Function
CPU SELECT (I)
3,4
This CPU can be used in both the
Connector Board and Controller.
When using as CPU in the Connector
Board, set pins as follows:
Pin 3 = HIGH
Pin 4 = LOW
(Already set on PCB. Cannot be
changed)
MODEL SELECT (I)
5
Set to LOW when using in G16.
(Already set on PCB. Cannot be
changed.)
M-MODE SELECT (I)
59, 60
Selects the bargraph mode. (Changed
by System Control)
Pin 59 - LOW .
r>- t aw Calibration mode
Pm 60 = LOW
Pin 59 = HIGH Permanent peak
Pin 60 = LOW hold mode
Pin 59 = LOW Temporary peak
Pin 60 = HIGH hold mode
Pin 59 = HIGH
Pin 60 = HIGH Normal mode
This port is also used for communicating
with System Control in the 2nd MODE
(This, however, is on condition that
“ 2nd mode ON/OFF ” port is ON -
HIGH).
In this case, it will be —
C-CLK (I) pin 59
C-DATA (I) pin 60
