15.3 FLASH DEVICES ONLY
15.3.1 Timer A Restrictions in Flash Devices
In Flash devices, Timer A functionality has the fol-
lowing restrictions:
– TAOC2HR and TAOC2LR registers are write
– Input Capture 2 is not implemented
– The corresponding interrupts cannot be used
152/154
only
(ICF2, OCF2 forced by hardware to zero)
15.3.2 External clock source with PLL
External clock source is not supported with the
PLL enabled.
15.3.3 39-Pulse ICC Entry Mode
ICC mode entry using ST7 application clock (39
pulses) is not supported. External clock mode
must be used (36 pulses). Refer to the ST7 Flash
Programming Reference Manual.
