Alternate counter register (ACR)

These two read-only 16-bit registers contain the same value but with the difference that
reading the ACLR register does not clear the TOF bit (timer overflow flag), located in the
status register, (SR),
alternate counter register) on page
Writing in the CLR register or ACLR register resets the free running counter to the FFFCh
value. Both counters have a reset value of FFFCh (this is the only value which is reloaded in
the 16-bit timer). The reset value of both counters is also FFFCh in One Pulse mode and
PWM mode.
The timer clock depends on the clock control bits of the CR2 register, as illustrated in
Table

/8 or an external frequency.
Counter high register (CHR) is the most significant byte (MSB).
Counter low register (CLR) is the least significant byte (LSB).
Alternate counter high register (ACHR) is the MSB.
Alternate counter low register (ACLR) is the LSB.
