Global Timer Module
This section describes the DC and AC electrical specifications for the global timer module (GTM) of the MPC8610.
2.13.1
GTM DC Electrical Characteristics
Table 39 provides the DC electrical characteristics for the MPC8610 global timer module pins, including GTMn_TINn,
GTMn_TOUTn, GTMn_TGATEn, and RTC.
2.13.2
GTM AC Timing Specifications
Table 40 provides the GTM input and output AC timing specifications.
Figure 21 provides the AC test load for the GTM.

Notes:
1. Input specifications are measured from the 50 percent level of the signal to the 50 percent level of the rising edge of CLKIN.
Timings are measured at the pin.
2. Timer inputs and outputs are asynchronous to any visible clock. Timer outputs should be synchronized before use by external
synchronous logic. Timer inputs are required to be valid for at least tGTIWID ns to ensure proper operation.
3. The minimum pulse width is a function of the MPX/platform clock. The minimum pulse width must be greater than or equal
to 4 times the MPX/platform clock period.
