Doc ID 15400 Rev 2
Note:
"0" means logic low and "1" means logic high. When there is NO CLOCK output, the CLKx
pin stays at logic low. "X" means don't care. This is an active high truth table. Refer to
Section 3.2: Enable polarity for the detailed enable active high/low options.
3.2
Enable polarity
In different applications, the user may have different requirements for enable active high or
active low (enable polarities). MCREQ is active low. STMicroelectronics offers different
solutions for the user to obtain different enable polarities.
In the STCD22x0 and STCD24x0, the user can configure the enable active high or active
low on the PC board by connecting OPT1 and OPT2 to either VCC or ground. Refer to
Table 7 for detailed information.
In the STCD23x0, STMicroelectronics offers 4 enable polarity options by factory
programming for the user. Refer to
Table 7 for detailed information.
The user should note that OPT1 and OPT2 must be connected to either VCC or GND on the
PC board and floating on these pins could cause problems.
