7.2.4
FLPWCR enables or disables a transition to the flash memory power-down mode when the LSI
switches to subactive mode. There are two modes: mode in which operation of the power supply
circuit of flash memory is partly halted in power-down mode and flash memory can be read, and
mode in which even if a transition is made to subactive mode, operation of the power supply
circuit of flash memory is retained and flash memory can be read.
7.2.5
Bit 7 (FLSHE) in FENR enables or disables the CPU access to the flash memory control registers,
FLMCR1, FLMCR2, EBR1, and FLPWCR.
7.3
There are two modes for programming/erasing of the flash memory; boot mode, which enables on-
board programming/erasing, and programmer mode, in which programming/erasing is performed
with a PROM programmer. On-board programming/erasing can also be performed in user
program mode. At reset-start in reset mode, the series of HD64F3664 changes to a mode
depending on the TEST pin settings, NMI pin settings, and input level of each port, as shown in
table 7.1. The input level of each pin must be defined four states before the reset ends.

Description
Power-Down Disable
When this bit is 0 and a transition is made to subactive
mode, the flash memory enters the power-down mode.
When this bit is 1, the flash memory remains in the
normal mode even after a transition is made to subactive
mode.
Reserved
These bits are always read as 0.
Description
Flash Memory Control Register Enable
Flash memory control registers can be accessed when
this bit is set to 1. Flash memory control registers cannot
be accessed when this bit is set to 0.
Reserved
These bits are always read as 0.
