DETAIL OF CONTROL BITS AND REGISTER MAPPING
Entering into LP Mode Using Random Code
- LP mode using Random Code must be selected in INIT
mode via bit 7 of the INIT MISC register.
- In Normal mode, read the Random Code using 0x1D00 or
0x1D80 command. The 3 Random Code bits are available on
MISO bits 2,1 and 0.
- Write LP mode by inverting the 3 random bits.
Example - Select LP VDD OFF without cyclic sense and
FWU:
1. in hex: 0x5C60 to enter in LP VDD OFF mode without
using the 3 random code bits.
2. if Random Code is selected, the commands are:
- Read Random Code: 0x1D00 or 0x1D80,
MISO report in binary: bits 15-8, bits 7-3, Rnd_[2], Rnd_[1],
Rnd_[0].
- Write LP VDD OFF mode, using Random Code inverted:
in binary: 0101 1100 0110 0 Rnd_b[2], Rnd_b[1], Rnd_b[0].
Table 30 summarizes these commands
Table 31 describes MISO bits 7-0, used to decode the
device’s current mode.
Table 32 describes the SAFE and DEBUG bit decoding.
