88 FLASH-2 Memory MOTOROLA

5.9 Low-Power Modes

The WAIT and STOP instructions will place the MCU in low power

consumption standby modes.

5.9.1 WAIT Mode

Putting the MCU into wait mode while the FLASH is in read mode does

not affect the operation of the FLASH memory directly; however, no

memory activity will take place since the CPU is inactive.

The WAIT instruction should not be executed while performing a

program or erase operation on the FLASH. Wait mode will suspend any

FLASH program/erase operations and leave the memory in a Standby

Mode.

5.9.2 STOP Mode

Putting the MCU into stop mode while the FLASH is in read mode does

not affect the operation of the FLASH memory directly; however, no

memory activity will take place since the CPU is inactive.

The STOP instruction should not be executed while performing a

program or erase operation on the FLASH. Stop mode will suspend any

FLASH program/erase operations and leave the memory in a Standby

Mode.

NOTE: Standby Mode is the power saving mode of the FLASH module, in which

all internal control signals to the FLASH are inactive and the current

consumption of the FLASH is minimum.

6.2 Introduction

This section describes the 512 bytes of electrically erasable

programmable read-only memory (EEPROM) residing at address range

$0800 to $09FF. There are 1024 bytes of EEPROM available on the

MC68HC908AS60A and MC68HC908AZ60A which are physically

located in two 512 byte arrays. For information relating to the array

covering address range $0600 to $07FF please see EEPROM-2

Memory on page 109.
