2.3.4 VREGEN — Voltage Regulator Enable Pin
This input only pin enables or disables the on-chip voltage regulator.
2.3.5 XFC — PLL Loop Filter Pin
PLL loop filter. Please ask your Motorola representative for the interactive application note to compute
PLL loop filter elements. Any current leakage on this pin must be avoided.

2.3.6 BKGD / TAGHI / MODC — Background Debug, Tag High, and Mode Pin
The BKGD/TAGHI/MODC pin is used as a pseudo-open-drain pin for the background debug
communication. In MCU expanded modes of operation when instruction tagging is on, an input low on
this pin during the falling edge of E-clock tags the high half of the instruction word being read into the
instruction queue. It is used as a MCU operating mode select pin during reset. The state of this pin is
latched to the MODC bit at the rising edge of RESET.
2.3.7 PAD15 / AN15 / ETRIG1 — Port AD Input Pin of ATD1
PAD15 is a general purpose input pin and analog input AN7 of the analog to digital converter ATD1. It
can act as an external trigger input for the ATD1.
2.3.8 PAD[14:08] / AN[14:08] — Port AD Input Pins ATD1
PAD14 - PAD08 are general purpose input pins and analog inputs AN[6:0] of the analog to digital
converter ATD1.
2.3.9 PAD07 / AN07 / ETRIG0 — Port AD Input Pin of ATD0
PAD07 is a general purpose input pin and analog input AN0 of the analog to digital converter ATD0. It
can act as an external trigger input for the ATD0.
