CONTROL PIN CHARACTERISTICS (Cont’d)
12.9.2 ICCSEL/VPP Pin
Subject to general operating conditions for VDD, fCPU, and TA unless otherwise specified.
Figure 109. Two typical Applications with ICCSEL/VPP Pin
2)
Notes:
1. Data based on design simulation and/or technology characteristics, not tested in production.
2. When ICC mode is not required by the application ICCSEL/VPP pin must be tied to VSS.
12.10 TIMER PERIPHERAL CHARACTERISTICS
Subject to general operating conditions for VDD, fOSC, and TA unless otherwise specified.
Refer to I/O port characteristics for more details on the input/output alternate function characteristics (out-
put compare, input capture, external clock, PWM output...).
