AT91SAM7XC512/256/128
Flash Programming Interface, is forbidden. This ensures the confidentiality of the code pro-
grammed in the Flash.
This security bit can only be enabled, through the Command “Set Security Bit” of the EFC User
Interface. Disabling the security bit can only be achieved by asserting the ERASE pin at 1, and
after a full flash erase is performed. When the security bit is deactivated, all accesses to the
flash are permitted.
It is important to note that the assertion of the ERASE pin should always be longer than 220 ms.
As the ERASE pin integrates a permanent pull-down, it can be left unconnected during normal
operation. However, it is safer to connect it directly to GND for the final application.
8.5.5
Non-volatile Brownout Detector Control
Two general purpose NVM (GPNVM) bits are used for controlling the brownout detector (BOD),
so that even after a power loss, the brownout detector operations remain in their state.
These two GPNVM bits can be cleared or set respectively through the commands “Clear Gen-
eral-purpose NVM Bit” and “Set General-purpose NVM Bit” of the EFC User Interface.
GPNVM Bit 0 is used as a brownout detector enable bit. Setting the GPNVM Bit 0 enables
the BOD, clearing it disables the BOD. Asserting ERASE clears the GPNVM Bit 0 and thus
disables the brownout detector by default.
The GPNVM Bit 1 is used as a brownout reset enable signal for the reset controller. Setting
the GPNVM Bit 1 enables the brownout reset when a brownout is detected, Clearing the
GPNVM Bit 1 disables the brownout reset. Asserting ERASE disables the brownout reset by
default.
8.5.6
Calibration Bits
Eight NVM bits are used to calibrate the brownout detector and the voltage regulator. These bits
are factory configured and cannot be changed by the user. The ERASE pin has no effect on the
calibration bits.
8.6
Fast Flash Programming Interface
The Fast Flash Programming Interface allows programming the device through either a serial
JTAG interface or through a multiplexed fully-handshaked parallel port. It allows gang-program-
ming with market-standard industrial programmers.
The FFPI supports read, page program, page erase, full erase, lock, unlock and protect
commands.
The Fast Flash Programming Interface is enabled and the Fast Programming Mode is entered
when the TST pin and the PA0 and PA1 pins are all tied high.
8.7
SAM-BA Boot Assistant
The SAM-BA Boot Assistant is a default Boot Program that provides an easy way to program in-
situ the on-chip Flash memory.
The SAM-BA Boot Assistant supports serial communication via the DBGU or the USB Device
Port.
Communication via the DBGU supports a wide range of crystals from 3 to 20 MHz via
software auto-detection.
