76 / 187 page  ST72321BRx, ST72321BARx ST72321BJx, ST72321BKx 76/187 16-BIT TIMER (Cont’d) Notes: 1. After a processor write cycle to the OCiHR reg- ister, the output compare function is inhibited until the OCiLR register is also written. 2. If the OCiE bit is not set, the OCMPi pin is a general I/O port and the OLVLi bit will not appear when a match is found but an interrupt could be generated if the OCIE bit is set. 3. In both internal and external clock modes, OCFi and OCMPi are set while the counter value equals the OCiR register value (see Fig- ure 8 for an example with fCPU/2 and Figure 9 for an example with fCPU/4). This behavior is the same in OPM or PWM mode. 4. The output compare functions can be used both for generating external events on the OCMPi pins even if the input capture mode is also used. 5. The value in the 16-bit OCiR register and the OLVi bit should be changed after each suc- cessful comparison in order to control an output waveform or establish a new elapsed timeout. Forced Compare Output capability When the FOLVi bit is set by software, the OLVLi bit is copied to the OCMPi pin. The OLVi bit has to be toggled in order to toggle the OCMPi pin when it is enabled (OCiE bit = 1). The OCFi bit is then not set by hardware, and thus no interrupt request is generated. The FOLVLi bits have no effect in both One Pulse mode and PWM mode. Figure 49.
