During reset, certain module configurations depend on whether emulation mode is active as determined
by the state of the internal emulation signal.
27.6.3
During reset configuration, the CS0 chip select pin is optionally configured to select an external boot
device. In this case, the V (valid) bit in the CSMR0 register is ignored, and CS0 is enabled after reset. CS0
is asserted for the initial boot fetch accessed from address 0x0000_0000 for the Stack Pointer and address
0x0000_0004 for the program counter (PC). It is assumed that the reset vector loaded from address
0x0000_0004 causes the CPU to start executing from external memory space decoded by CS0.
27.6.4
Output pad strength is determined during reset configuration as shown in
the output pad strength configuration can be changed by programming the LOAD bit of the chip
configuration register.
27.6.5
The clock mode is selected during reset by the CLKMOD pins and reflected in the PLLMODE, PLLSEL,
and PLLREF bits of SYNSR. After reset is exited, the clock mode cannot be changed.

When Flash security is enabled, the chip will boot in single chip mode
regardless of the external reset configuration.
Modifying the default configurations is possible only if the external RCON pin is asserted low.
