The first byte output by this command is the value 146 (092h), which represents the number of peripheral registers output. Table 25

lists the remaining 356 bytes output by this command.

ADDENDUM TO SECTION 17: IN-SYSTEM PROGRAMMING (JTAG)

The MAXQ2000 provides two different interfaces for in-system programming (bootloader) operations.

• JTAG TAP interface

• Serial port 0 (UART) interface

To use either of these interfaces for in-system programming, the SPE and PSS[1:0] bits must be set through the JTAG TAP interface.

This is done while the device is held in reset, using the system-programming instruction as described in the MAXQ Family User’s Guide.

It is also possible for the MAXQ2000 to bootstrap itself into in-system programming mode by setting the proper bits in the In-Circuit

Debug Flag (ICDF) register and invoking a reset. The procedure for invoking in-system programming in this manner must be defined

by the application firmware.

Bit 0: (ICDF.0) Reserved
