stabilized. Then hold the RESET input to low for at least 20 system clocks (16 μs at fc = 40
MHz).
program counter settings. CPU internal registers not mentioned above do not change when
the reset is released.
The operation of memory controller cannot be insured until power supply becomes stable after power-on reset. The
external RAM data provided before turning on the TMP92CM22 may be spoiled because the control signals are
unstable until power supply becomes stable after power on reset.
When resetting the TMP92CM22 microcontroller, ensure that the power supply voltage
When the reset has been accepted, the CPU performs the following:
When the reset is released, the CPU starts executing instructions according to the
When the reset is accepted, the CPU sets internal I/O, ports and other pins as follows.
Figure 3.1.1 shows the timing of a reset for the TMP92CM22.
Internal reset is released as soon as external reset is released and
