RM7965A-900UI 900 MHz 64-bit Microprocessor Data Sheet
4.21 JTAG Interface
The RM7965A interface supports JTAG boundary scan in conformance with IEEE 1149.1. The
JTAG interface is useful for checking the integrity of the processor’s pin connections.
4.22 Reset Sequence
The RM7965A uses the same reset interface that is used on the RM7000 and RM5200 product
families. This single reset interface is used to reset the entire system.
Both power on reset and cold reset completely initialize the RM7965A. The configuration mode
bit stream is read into the device to configure the E9000 core and the external bus interface (see
Section 8). The configuration stream is read in when the VccOK input signal has been asserted
and ColdReset* and Reset* remain asserted. During this time, the PLL is achieving lock.
