Local Bus

This section describes the DC and AC electrical specifications for the local bus interface of the

MPC8360E/58E.

9.1

Local Bus DC Electrical Characteristics

Table 39 provides the DC electrical characteristics for the local bus interface.

9.2

Local Bus AC Electrical Specifications

Table 40 describes the general timing parameters of the local bus interface of the device.

———

Notes:

1. The timer can operate on rtc_clock or tmr_clock. These clocks get muxed and any one of them can be selected. Min and

Max requirement for both rtc_clock and tmr_clock are the same.

2. These are asynchronous signals.

3. Inputs need to be stable at least one TMR clock.
