Purchase of I
Added new External Connections section
Removed RP external resistor
Changed ORed to ANDed in External interrupts paragraph, to read “If several input pins, con-
nected to the same interrupt vector, are configured as interrupts, their signals are logically AN-
Ded before entering the edge/level detection block”.
Added note ”Any modification of one of these two bits resets the interrupt request related to
this interrupt vector.”
Added clamping diodes to I/O pin figure and table
Added sections on low power modes and interrupts to peripheral descriptions
Changed 16-bit Timer chapter
Added details to description of FOLV1 and FOLV2 bits
Added ADC recommended external connections
Added Reset characteristics section
Added min. value for V
Added figure to ADC Converter Specification
Removed ST72331 ROM device (supported by ST72334)
SPR2 bit reinstated in SPI chapter
