Merge with STM8A reference manual (RM0009).

Renamed low power modes, Halt, Active-halt, Wait, and Run in the

whole document.

Added overview of STM8S and STM8A device families on

coverpage.

Section 2: Boot ROM: added LIN mode configuration.

Section 3: Memory and register map:

– Updated Section 3.1.1: Memory map to cover both STM8A and

STM8S devices.

– Added Section 3.1.2: Stack handling.

Section 4: Flash program memory and data EEPROM

– Updated Flash program memory and SRAM size for medium

density STM8S and STM8A devices in Section 4.4.1: STM8S and

STM8AF memory organization.

– Added Note 1 below Figure 7: Flash memory and data EEPROM

organization on medium density STM8S and STM8AF.

– Added 32 Kbyte and 128 Kbyte STM8A devices and Section 4.4.2:

Memory access/ wait state configuration.

– Section 4.5.1: Readout protection: added DM mode when readout

protection is enabled, and Section : Temporarily removing the

readout protection.

– Added case of FLASH_CR1/FLASH_CR2 access during memory

write operation in Section 4.6.1: Read-while-write (RWW).

– Moved all information related to temporary memory unprotection to

dedicated application note.

Section 7: Power supply:

– Removed minimum VCAP value in Power section overview.

Section 8: Reset (RST):

– Changed EMS to EMC.

– Added Section 8.1: “Reset state” and “under reset” definitions.

– Replace numerical values by tOP(NRST) and tINFP(NRST) in

Section 8.2: Reset circuit description.

Section 9: Clock control (CLK):

– Added Table 14: Devices with 4 trimming bits and Table 15:

Devices with 3 trimming bits in Section 9.1.2: HSI (high-speed

internal) clock signal.

– Updated CLK_HSITRIMR, CLK_SWIMCCR, and CLK_SWCR

reset values.

Section 10: Power management:

– Updated Fast clock wakeup in Section 10.2.3: Active-halt modes.

Section 6: Interrupt controller (ITC):

– Added caution note concerning interrupt disabling inside an ISR in

Section 6.2: Interrupt masking and processing flow.

– Added Push CC instruction in Table 11: Dedicated interrupt

instruction set.

– Removed note 3 in Section 6.2.1: Servicing pending interrupts.

Removed case of TRAP interruption by TLI in Section 6.2.2:

Interrupt sources.
