PMXCONFIG
PMXCONFIG is a read-only register containing the
iC-PMX revision and the state of the four configura-
tion pins of the iC-PMX. These values are read by the
iC-TW14 from iC-PMX address 0x07 and the iC-PMX
Read POS command address 0x0F (respectively) at
startup.
See Self-Sustained Operation Mode Selection and Po-
sition Data in Period Counter Mode with a Data Process-
ing FRAM and FRAM Access in the iC-PMX datasheet
for more information. See SPI Slave Interface in the
iC-PMX datasheet for more information on the iC-PMX
revision.
STATUS
STATUS is a read-only register containing bits that indi-
cate the status of the iC-TW14. STATUS bits are active
as long as the corresponding condition is true.

Table 11: iC-PMX Configuration
STATUS.CF = 1 indicates that the iC-PMX is not cor-
rectly configured for the iC-TW14. Specifically, STA-
TUS.CF = 1 if iC-PMX pin C0 or pin C1 are high. C0
and C1 must both be low for use with the iC-TW14.
STATUS.CF = 1 also sets STATUS.STOP = 1.
STATUS.NPRE = 1 indicates that the iC-TW14’s NPRE
input is low (active). See PRESET PIN (NPRE) on page
24 for more information.
