When the MPU writes a non-zero value to RCMD,
the 71M6543 issues a command to the cor-
responding isolated sensor selected with
RCMD[1:0]. When the command is complete, the
71M6543 clears RCMD[4:2]. The command code
itself is in RCMD[4:2].
The 71M6543 sets these bits to indicate that a
parity error on the isolated sensor has been de-
tected. Once set, the bits are remembered until
they are cleared by the MPU.
The CHOP settings for the isolated sensors.
00 – Auto chop. Change every multiplexer frame.
01 – Positive
10 – Negative
11 – Same as 00
The read buffer for 71M6xx3 read operations.
Controls how the 71M6543 drives the 71M6xx3
power pulse. When set, the power pulse is driven
high and low. When cleared, it is driven high
followed by an open circuit fly-back interval.
Enables the isolated remote sensor interface and
re-configures pins IADC2-IADC3 as a balanced
pair digital remote interface.
Enables the isolated remote sensor interface and
re-configures pins IADC4-IADC5 as a balanced
pair digital remote interface.
Enables the isolated remote sensor interface and
re-configures pins IADC6-IADC7 as a balanced
pair digital remote interface.
