STM8L151F3 Bootloader

Have anybody any information on bootloader interface configuration for I couldn't find direct instructions on port connections. I assume they should be PC2 and PC3 pins (due to SYSCFG->RMPCR1 default value) but there is some problem: STM8LF151F3 in UFQFPN20 package have no these pins.

So is it even possible to use bootloader in UART mode with this package or I should look towards usin SPI interface? By the way, which pins do bootloader require for SPI? Maybe PB5, PB6, PB7 ?
