13.4 I/O Signals
The following paragraphs describe the CGM I/O signals.
13.4.1 CGM Power Supply Pins (V_DDA, V_SSA0, V_SSA1)
V_DDA is the power supply pin, V_SSA0 and V_SSA1 are the ground pins for
the analog portions of both CGMs.
13.4.2 CGM1 Voltage Regulator Out (V_REGA0)
3.3V output of the on-chip voltage regulator for analog portions. Connect
V_REGA0 directly to V_REGA1 as shown in Figure 13-3.
13.4.3 CGM2 Voltage Regulator In (V_REGA1)
3.3V input for CGM2 analog portions. Connect V_REGA0 directly to
V_REGA1 as shown in Figure 13-3.
