17.5.1
CALMM
INSTRUCTION
This instruction enters the device into the calibration
mode. This mode enables the shift register for loading and
allows programming of the non-volatile OTP cells to take
place. If the seal bit is set, then this mode cannot be
accessed and the instruction will be ignored. Once in
calibration mode, data may be loaded into the shift register
via the ‘LOAD0’ and ‘LOAD1’ instructions (on the falling
edge of SCLK).
The CALMM mode may be left by setting the CALMM bit
to logic 0. Reset will also clear this mode.
The programming can only take place when OTP Switch
Enable (OSE) has been set to logic 1. This bit enables the
V
OTPPROG
input to be passed to the OTP cells. This allows
V
OTPGATE
to be tied to SCLH/SCE on the module for
normal operation. Reset will also clear this mode.
17.5.2
R
EFRESH INSTRUCTION
The action of the ‘refresh’ instruction is to force the OTP
shiftregister to reloadfrom thenon-volatile OTPcells. This
instruction takes up to 5 ms to complete. During this time
all other instructions may be sent.
In the OM6208 the ‘refresh’ instruction is associated with
the ‘DON’ instruction so that the shift register is
automatically refreshed every time DON is enabled or
disabled.
Note: If this instruction is sent while in power save mode,
the DON bit will be updated but the refreshing is delayed
until the device leaves power-down.
