Read-only Mode
The microcomputer enters the read-only mode by applying V
PP
L
to the V
PP
pin. In this mode, the user can input the address of a
memory location to be read and the control signals at the timing
shown in Figure 67, and the M38869FFAHP/GP will output the
contents of the user’s specified address from data I/O pin to the
external. In this mode, the user cannot perform any operation
other than read.
Fig. 67 Read timing
Read/Write Mode
The microcomputer enters the read/write mode by applying V
PP
H
to the V
PP
pin. In this mode, the user must first input a software
command to choose the operation (e. g., read, program, or erase)
to be performed on the flash memory (this is called the first cycle),
and then input the information necessary for execution of the com-
mand (e.g, address and data) and control signals (this is called
the second cycle). When this is done, the M38869FFAHP/GP ex-
ecutes the specified operation.
Table 21 shows the software commands and the input/output in-
formation in the first and the second cycles. The input address is
latched internally at the falling edge of the WE input; software
commands and other input data are latched internally at the rising
edge of the WE input.
The following explains each software command. Refer to Figures 68
to 70 for details about the signal input/output timings.
