REVISION HISTORY

This data sheet revision history highlights the technical changes made to the SPRS007C device-specific data

sheet to make it an SPRS007D revision.

Scope: This document has been reviewed for technical accuracy; the technical content is up-to-date as of the

specified release date with the following changes.

NO.

ADDITIONS/CHANGES/DELETIONS

Added “This pin must be tied directly to DVDD to enable HPI.” to the HPIENA description and “This pin must be tied directly to

DVDD to enable HPI16 mode.” to the HPI16 description in Table 2−2. Also deleted “Internally pulled low.” from the HPI16

description.

Added the following to Section 3.9: “Since the Timer1 output is multiplexed externally with the HINT output, the HPI must be

disabled (HPIENA input pin = 0) if the Timer1 output is to be used. The Timer1 output also has a dedicated enable bit in the

General Purpose I/O Control Register (GPIOCR) located at data memory address 003Ch. If the external Timer1 output is to

be used, in addition to disabling the HPI, the TOUT1 bit in the GPIOCR must also be set to 1.”

Changed the parenthetical statement “(such as the McBSPs)” in Section 3.12. to read “(such as the McBSPs, but not the

UART)”

Added the following footnote to Table 3−12: “Note that the UART DMA synchronization event is usable as a synchronization

event only, and is not usable for transferring data to or from the UART. The DMA cannot be used to transfer data to or from

the UART.”

Changed Figure 3−23, bit 15 from “Reserved” to “TOUT1”.

Added the following paragraph to Section 3.14.2: “Bit 15 of the GPIOCR is also used as the Timer1 output enable bit, TOUT1.

The TOUT1 bit enables or disables the Timer1 output on the HINT/TOUT1 pin. If TOUT1 = 0, the Timer1 output is not

available externally; if TOUT1 = 1, the Timer1 output is driven on the HINT/TOUT1 pin. Note also that the Timer1 output is

only available when the HPI is disabled (HPIENA input pin = 0).”

Changed the IDDC parameter from “60” to “42” in the Electrical Characteristics Over Recommended Operating Case

Temperature Range table.
