Programmable Interrupt Controller
Figure 28. Local Bus Signals, GPCM/UPM Signals for LCCR[CLKDIV] = 8 or 16 (PLL Bypass Mode)
11 Programmable Interrupt Controller
In IRQ edge trigger mode, when an external interrupt signal is asserted (according to the programmed
polarity), it must remain the assertion for at least 3 system clocks (SYSCLK periods).
12 JTAG
This section describes the DC and AC electrical specifications for the IEEE 1149.1 (JTAG) interface of
the MPC8548E.
