Legend: x=undefined, R/W=read/write
Notes:
1. The contents of the I/O port DR registers are readable only in output configuration. In input configura-
2. The bits associated with unavailable pins must always keep their reset value.
3. The Timer A Input Capture 2 pin is not available (not bonded).
4. The Timer A Output Compare 2 pin is not available (not bonded).
Caution: The TAIC2HR and TAIC2LR registers and the ICF2 and OCF2 flags are not present in the
ST72F324L but are present in the emulator. For compatibility with the emulator, it is recommended to per-
form a dummy access (read or write) to the TAIC2LR and TAOC2LR registers to clear the interrupt flags.

tion, the values of the I/O pins are returned instead of the DR register contents.
The TAIC2HR and TAIC2LR registers are not present. Bit 4 of the TACSR register (ICF2) is forced
by hardware to 0. Consequently, the corresponding interrupt cannot be used.
The TAOC2HR and TAOC2LR Registers can be used in PWM mode or for timebase generation.
The TAOC2HR and TAOC2LR Registers are write only, reading them will return undefined values.
Bit 3 of the TACSR register (OCF2) is forced by hardware to 0. Consequently, the corresponding in-
terrupt cannot be used.
