NOTE: many host microcontrollers cannot be operated from the TRC103 buffered clock output if sleep cycling is
planned. In sleep mode, the TRC103 buffered clock output is disabled, which will disable the microcontroller
unless it is capable of automatically switching to an internal clock source when external clocking is lost.
TRC103 sleep related mode switching is configured in MCFG00 bits 7..5 as follows:
When switching from sleep mode to standby, the crystal oscillator will be active in no more than 5 ms. Switching
from standby to synthesizer mode, the PLL will lock in less than 0.5 ms. PLL lock can be monitored on Pin 23 of
the TRC103. The radio can then be switched to either transmit or receive mode. When switching from any other
mode back to sleep, the TRC103 will drop to its sleep mode current in less than 1 ms.
