MC13224 serial bootloader

Is there any way to enable the serial bootloader on the MC13224 via software without having to set ADC2_VREFH pin to low and ADC2_VREFL pin to high?

Thanks,

Daniel.

Setting ADC2_VREFH low and ADC2_VREFL high on reset triggers a flash erase.

Setting UART1_RTS low on reset will cause the bootloader to watch UART1 if there isn't a valid image in flash, SPI, or I2C.

I suppose it wouldn't be too hard to find the ROM address for the UART1 bootloader and jump to there...
