Dear,

New revision of

http://STR73x Reference manual

http://www.st.com/stonline/products/literature/rm/13682.pdf

Rev2 is available for download from the web site;

http://www.st.com/mcu/familiesdocs-86.html

Here below, changes compared to the last revision Rev1;

+ Updated Section 14.3.10:''Pulse width modulation mode''

- Added period formula when OCBR> OCAR

- Updated period formula when OCBR and OCAR are loaded with FFFCh.

+ Modified Section 6.1.2:''Alternate function I/O (AF)''

- For alternate function inputs, the port must be configured in Input

mode and the input pin must be driven externally.

+ Added Section 11.3.3:''RTC flag assertion''

- Added Note: If RTC interrupts are used during Run, Slow, WFI or LPWFI

modes the RTC clock must be at least 4 times slower than MCLK clock.

+ Modified Section 11.4.3:''RTC Prescaler Load Register High (RTC_PRLH)''

- Bits 3:0 = PRL[19:16]: These bits are used to define the counter clock frequency according to the following formula:

fTR_CLK = fRTC/64/2 ; if PRL[19:0] =0

fTR_CLK = fRTC/64/(PRL[19:0]+1) ; if PRL[19:0] > 0

+ Updated Section 11.4.4:''RTC Prescaler Load Register Low (RTC_PRLL)''

- Bits 15:0 = PRL[15:0]: These bits are used to define the counter clock frequency according to the following formula:

fTR_CLK = fRTC/64/2 ; if PRL[19:0] =0

fTR_CLK = fRTC/64/(PRL[19:0]+1) ; if PRL[19:0] > 0

- Added note: The reset value sets the TR_CLK signal period to 1 sec

for an input clock of 32 kHz.

+ Updated Section 18.2.5:''Start-up status''

- The MSTR bit must be set high and then the BSPI must be enabled.

+ Updated Section 19.4.6:''UART control register (UARTn_SR)''

- RxBufFull changed to RxBufNotEmpty.

+ Updated Section 17.4:''Interrupts''

- SCLFAL signal removed from figure 62:''Event flags and interrupt generation''

+ Added Section 22.1.1:''JTAG ID code''

Best Regards ;)
