Section 2– Conﬁguration, Clocking, Low Power Modes, and

Internal Memory Map

1. SCCE2 Register

In section 2-24, in Table 2-6, the SCCE2 register should be 8 bits wide, not 16 bits as shown.

Section 3 - Sytstem Integration Block

1. Periodic Interrupt Timer equation

In section 3.7.4.2, in the periodic interrupt timer period equation, the "+1" should be carried

through the equations.

Section 5 - Signal Description

1. Bus Request Signal description

In section 5.8, the Bus Request signal is shown incorrectly in figure 5-7 an d the description

below the figure is incorrect. The pin is shown as bidirectional, but should be an out put only.

The description shoud read, “This signal is an open-drain output request signal from the

IDMA and SDMA when the internal EC000 core is disabled.”

2. Port A / Bootstrap Mode description

In section 5.14 in the “NOTE” section, “To enable Boot from SCC2” should be replaced with

“To enable Boot from SCC1.” The Bootstrap mode is only available on SCC1.
