10.3 16-BIT TIMER
10.3.1 Introduction
The timer consists of a 16-bit free-running counter
driven by a programmable prescaler.
It may be used for a variety of purposes, including
pulse length measurement of up to two input sig-
nals (input capture) or generation of up to two out-
put waveforms (output compare and PWM).
Pulse lengths and waveform periods can be mod-
ulated from a few microseconds to several milli-
seconds using the timer prescaler and the CPU
clock prescaler.
Some devices of the ST7 family have two on-chip
16-bit timers. They are completely independent,
and do not share any resources. They are syn-
chronized after a Device reset as long as the timer
clock frequencies are not modified.
This description covers one or two 16-bit timers. In
the devices with two timers, register names are
prefixed with TA (Timer A) or TB (Timer B).

10.3.3 Functional Description
10.3.3.1 Counter
The main block of the Programmable Timer is a
16-bit free running upcounter and its associated
16-bit registers. The 16-bit registers are made up
of two 8-bit registers called high & low.
Counter Register (CR):
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),
(see note at the end of paragraph titled 16-bit read
sequence).
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 tim-
er). 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
Control
peats every 131 072, 262 144 or 524 288 CPU
clock cycles depending on the CC[1:0] bits.
The timer frequency can be f
or an external frequency.
