我没有看到需要时能什么,他说:硬件存储是通过HSB,软件存储通过地址序列,自动存储是默认的,我理解的就是按照datasheet上的原理图接就应该没有问题。
Hardware STORE activated by the HSB; Software STORE activated by an
address sequence; AutoStore on device power-down. The
AutoStore operation is a unique feature of QuantumTrap
technology and is enabled by default on the
CY14B104LA/CY14B104NA

Datasheet是这样写的:
A pull-up should be placed on WE to hold it inactive during power-up. This
pull-up is effective only if the WE signal is tristate during
power-up. Many MPUs tristate their controls on power-up. This
should be verified when using the pull-up. When the nvSRAM
comes out of power-on-RECALL, the MPU must be active or the
WE held inactive until the MPU comes out of reset.
