TMP92CZ26A
92CZ26A-294
3.13 16 bit timer / Event counter (TMRB)
The TMP92CZ26A incorporates two multifunctional 16-bit timer/event counter (TMRB0,
TMRB1) which have the following operation modes:
• 16 bit interval timer mode
• 16 bit event counter mode
• 16 bit programmable pulse generation mode (PPG)
Can be used following operation modes by capture function.
• Frequency measurement mode
• Pulse width measurement mode
Timer/event counter consists of a 16-bit up counter, two 16-bit timer registers (One of them
with a double-buffer structure), a 16-bit capture registers, two comparators, a capture input
controller, a timer flip-flop and a control circuit.
Timer/event counter is controlled by an 11-byte control SFR.Each channel(TMRB0,TMRB1)
operate independently.In this section, the explanation describes only for TMRB0 because each
channel is identical operation except for the difference as follows;
