If MS = ‘LOW’, then pins 22 and 23 are control bits S2 and S3 for
Port B only, as shown in the truth table on page 3.
Control pin used to choose which input signal is active, Port A or
Port B. If ‘LOW’, then Port A is active, if ‘HIGH’, then Port B is
active.

If MS = ‘LOW’, then pins 25-28 are control bits S7-S4, as shown
in truth table on page 3 of datasheet
Mode Select Pin. If MS = ‘HIGH’, then I2C control is active. Pins
25-28 are I
= ‘LOW’, then I2C control is inactive and pin programmability is
active. Pins 25-28 are control pins S7-S4 and pin 23 is S2 and pin
22 is S3.
No Connect.
Output bit, that provides information to user as to which port is
active, if SEL_OUT = ‘LOW’, then Port A is active, if SEL_OUT
= ‘HIGH’, then Port B is active. Only used when MS pin is
‘HIGH’

If MS = ‘LOW’, then pins 22 and 23 are control bits S2 and S3 for
Port A only, as shown in the truth table on page 3.
Output is enabled and normal when OE = ‘HIGH’. If OE =
‘LOW’, output is disabled and at Hi-Z
