Figure 3.
JTAG chaining inside the STR91xF
2.15.1 In-system-programming
The JTAG interface is used to program or erase all memory areas of the STR91xF device. The
pin RESET_INn must be asserted during ISP to prevent the CPU from fetching invalid
instructions while the Flash memories are being programmed.
Note that the 32 bytes of OTP memory locations cannot be erased by any means once
programmed by JTAG ISP or the CPU.
2.15.2 Boundary scan
Standard JTAG boundary scan testing compliant with IEEE-1149.1 is available on the majority
of pins of the STR91xF for circuit board test during manufacture of the end product. STR91xF
pins that are not serviced by boundary scan are the following:
JTAG pins JTCK, JTMS, JTDI, JTDO, JTRSTn, JRTCK
Oscillator input pins X1_CPU, X2_CPU, X1_RTC, X2_RTC
Tamper detect input pin TAMPER_IN (128-pin packages only)

2.15.3 CPU debug
The ARM966E-S CPU core has standard ARM EmbeddedICE-RT logic, allowing the STR91xF
to be debugged through the JTAG interface. This provides advanced debugging features
making it easier to develop application firmware, operating systems, and the hardware itself.
