Standby Status
It is possible to put the MSM82C51A-2 in “standby status”
When the following conditions have been satisfied the MSM82C51A-2 is in “standby status.”
(1) CS terminal is fixed at Vcc level.
(2) Input pins other CS , D0 to D7, RD, WR and C/D are fixed at Vcc or GND level (including
SYNDET in external synchronous mode).
Note:
When all output currents are 0, ICCS specification is applied.
