La recepción de UART no funciona en STM8S

Soy nuevo en stm8 (stm8s003f3p). He realizado el siguiente código, pero no pude encontrar el problema. La transmisión UART está funcionando pero no pudo recibir nada.

#include <iostm8s003f3.h>
#include <intrinsics.h>
#include <stdio.h>

void InitialiseSystemClock()

    CLK_ECKR = 0;                       //  Disable the external clock.
    while (CLK_ICKR_HSIRDY == 0);       //  Wait for the HSI to be ready for use.
    CLK_CKDIVR = 0;                     //  Ensure the clocks are running at full speed.
    CLK_PCKENR1 = 0xff;                 //  Enable all peripheral clocks.
    CLK_PCKENR2 = 0xff;                 //  Ditto.
    CLK_CCOR = 0;                       //  Turn off CCO.
    CLK_HSITRIMR = 0;                   //  Turn off any HSIU trimming.
    CLK_SWIMCCR = 0;                    //  Set SWIM to run at clock / 2.
    CLK_SWR = 0xe1;                     //  Use HSI as the clock source.
    CLK_SWCR = 0;                       //  Reset the clock switch control register.
