This ipo console command can be used to modify the ZAURA_RF_OscCtrl1
configuration variable. The value of the ZAURA_RF_OscCtrl1 variable deter-
mines the system clock frequency of the Z8F2480 MCU’s Internal Precision
Oscillator (IPO). The ZAURA RF Wireless Module library can be used with
IPO frequencies from 1.3842 MHz to 11.0592 MHz.
If the ipo command is issued without any parameters, the current IPO
frequency is displayed. If the <index> parameter is specified and contains
a value between 0 and 3, then the value of the
OscCtrl1 configuration
variable in Flash is updated and the system performs a reset procedure to
re-initialize all peripherals with the new system clock frequency.
The UART baud rate will be modified if the IPO frequency is changed to
or from the 1.3.824 MHz frequency, as indicated in Table 3.
