Read command
The microcomputer enters the read mode by inputting command
code “00
internal command latch at the rising edge of the WE input. When the
address of a memory location to be read is input in the second cycle,
with control signals input at the timing shown in Figure 9, the
M37753FFCFP and the M37753FFCHP output the contents of the
specified address from the data I/O pins to the external.

The read mode is retained until any other command is latched into
the command latch. Consequently, once the M37753FFCFP and the
M37753FFCHP enter the read mode, the user can read out the suc-
cessive memory contents simply by changing the input address and
executing the second cycle only. Any command other than the read
command must be input beginning from its command code over
again each time the user execute it. The contents of the command
latch immediately after power-on is 00
