Capture / compare (CAPCOM) units

Capture / compare (CAPCOM) units
The ST10F273M has two 16-channel CAPCOM units which support generation and control
of timing sequences on up to 32 channels with a maximum resolution of 200ns at 40 MHz
CPU clock.
The CAPCOM units are typically used to handle high speed I/O tasks such as pulse and
waveform generation, pulse width modulation (PMW), digital to analog (D/A) conversion,
software timing, or time recording relative to external events.
Four 16-bit timers (T0/T1, T7/T8) with reload registers provide two independent time bases
for the capture/compare register array.
The input clock for the timers is programmable to several prescaled values of the internal
system clock, or may be derived from an overflow/underflow of timer T6 in module GPT2.
This provides a wide range of variation for the timer period and resolution and allows precise
adjustments to application specific requirements. In addition, external count inputs for
CAPCOM timers T0 and T7 allow event scheduling for the capture/compare registers
relative to external events.
Each of the two capture/compare register arrays contain 16 dual purpose capture/compare
registers, each of which may be individually allocated to either CAPCOM timer T0 or T1 (T7
or T8, respectively), and programmed for capture or compare functions. Each of the 32
registers has one associated port pin which serves as an input pin for triggering the capture
function, or as an output pin to indicate the occurrence of a compare event.
When a capture/compare register has been selected for capture mode, the current contents
of the allocated timer will be latched (captured) into the capture/compare register in
response to an external event at the port pin which is associated with this register. In
addition, a specific interrupt request for this capture/compare register is generated.
Either a positive, a negative, or both a positive and a negative external signal transition at
the pin can be selected as the triggering event. The contents of all registers which have
been selected for one of the five compare modes are continuously compared with the
contents of the allocated timers.
When a match occurs between the timer value and the value in a capture / compare
register, specific actions will be taken based on the selected compare mode.
The input frequencies fTx, for the timer input selector Tx, are determined as a function of the
CPU clocks. The timer input frequencies, resolution and periods which result from the
selected prescaler option in TxI when using a 40 MHz CPU clock are listed in Table 34.
The numbers for the timer periods are based on a reload value of 0000h. Note that some
numbers may be rounded off to three significant figures.
Table 33.
Compare modes
Function
Mode 0
Interrupt-only compare mode; several compare interrupts per timer period are possible
Mode 1
Pin toggles on each compare match; several compare events per timer period are possible
Mode 2
Interrupt-only compare mode; only one compare interrupt per timer period is generated
