+# according to errata, we need to use vectreset rather than sysresetreq to
avoid lockup
+# There is a bug in the chip, which means that when using external debuggers
the chip
+# may lock up in certain CPU clock modes. Affected modes are operating the CPU
at
+# 24MHz derived from the 24MHz crystal, or 12MHz derived from the high
frequency RC
+# oscillator. If an external debugger tool asserts SYSRESETREQ, the chip will
lock up and
+# require a pin reset or power cycle.
