Table 7-2
When the host computer has completed downloading code into the MCU RAM, the host then sends a
RUN command, which executes an RTI, which sends control to the address on the stack pointer.
7.3.2 Baud Rate
The communication baud rate is dependant on oscillator frequency. The state of PTB3 also affects baud
rate if entry to monitor mode is by IRQ = V
pin is at logic zero upon entry into monitor mode, the divide by ratio is 512.
