2.5.9.3 5V Output for Clock Pad
2.6 Pad Groups
MPC555
USER’S MANUAL
This interface is used for a 5-V clock pad output. The drive select signal selects the
buffer for a 45- or 90-pF load.
A pad group is a set of pins that exhibits similar functional characteristics. Within a
group the individual pads may be of different types. The functionality of some pins is
defined based on the control bits that are set in the SIUMCR from the reset configura-
tion word. Refer to the section on pin functionality out of reset in the reset section of
the document.
The following is a list of pad groups which were obtained based on the 3-V / 5-V se-
lection from the information in the “pin configuration out of reset” tables. In other words,
each group receives a different encoded 3-V / 5-V select signal.
All pins that drive 3 V have the provision to choose between drive strengths for a 25-
pF load or a 50-pF load.
