(6) Standby Mode (see page 7)
The MSM81C55-5 is placed in standby mode when the high level at the CE input is latched
during the negative going edge of ALE. All input ports and the timer input should be pulled
up or down to either VCC or GND potential.
When using battery back-up, all ports should be set low or in input port mode. The timer
output should be set low. Otherwise, a buffer should be added to the timer output and the
battery should be connected to the power supply pins of the buffer.
By setting the reset input to a high level, the standby mode can be selected. In this case, the
command register is reset, so the ports automatically set to the input mode and the timer
stops.
