STM8S001J3 halt mode current is 4.5uA in datasheet, I get 1mA when tried

[DBans.1569]

1. Table 26 of STM8S001J3 page 49 of 85, shows current consumption in halt mode is 4.5uA typical, but when I put MCU in halt mode, i got current in 1mA range. Dont understand why?

2. I have broken small breakout board from stm8-so8-disco of STM8S001J3 so measuring its current only. Nothing else is connected on MCU. On Pin D6 an external 10K with pull up and 0.1uF decoupling capacitor is connected. Nothing else is on board,program once put by debugger and then it is disconnceted also. Please note its breakout board of STM8S001J3 from disco board not entire disco board, so no other component can consume current. On breakout board there are only three components: MCU, and two decoupling caps of vcap and vss.

3, Power supply is also very clean, its single cell lithium ion cell sitting at 3.7V around at the moment, no other noise source I see.

4. Below is code, dont understand what is consuming current so much? No switch toogling at the moment, switch toggle only when I press, currently measuring curent without any press also. Switch operation working correctly.

5. In code turned off all peripherals, put all pins in pull up or output low mode. Dont understand what is consuming current. Changed two boards also same result.

using IAR3.11.1 . Code put inside MCU is : Release, Optimization High speed.
