During reset, a 130-µA (maximum) resistor “weakly pulls” all input signals, with the exception of the
power-supply and clock-related signals, to a value based on conditions described in
“Electrical
CLKOUT, HRESET, and SRESET) are pulled only by the pull-up/pull-down.
2.6.1
The reset configuration word (RCW) defines the post-reset functionality of some multiplexed signals. For
details on these signals and how they are configured, refer to Section 7.5.2, “Hard Reset Configuration
Word.”
The 2.6-V bus related signals have selectable output buffer drive strengths that are controlled by the COM0
bit in the USIU’s system clock and reset control register (SCCR). The control is as follows:
2.6.2
While HRESET is asserted, the reset-configuration value is latched from the data bus into various bits on
the part. The function of many signals depends upon the value latched. If the value on the data bus changes,
then the function of various signals may also change. This is especially true if the reset configuration word
(RCW) comes from the Flash, because the Flash does not drive the RCW until 256 clocks after the start of
