PROGRAMMING
Write Register
The WRT_REG register handles three command bits
[b5:b7] and five data bits [b0:b4] as depicted in Table 1.
These bits are concatenated into a single byte to accelerate
the programming sequence. The register can be updated
when CS is low only.
Table 1. WRT_REG Bits Definitions
WRT_REG
The CRD_RST pin reflects the content of the MOSI
WRT_REG[b4] during the chip programming sequence.
Since this bit shall be Low to address the internal register of
the chip, care must be observed as this signal will be
immediately transferred to the CRD_RST pin.

10.When operating in Asynchronous mode, [b5:b7] are compared with the external voltage levels present pins C4/S0 and C8/S1 (respectively
pins 15 and 14).
11.The CRD_RST pin reflects the content of the MOSI WRT_REG[b4] during the chip programming sequence. Since this bit shall be Low to
address the internal register of the chip, care must be observed as this signal will be immediately transferred to the CRD_RST pin.
