When the MPU writes a non-zero value to RCMD,
the 71M6543F/H issues a command to the cor-
responding isolated sensor selected with
RCMD[1:0]. When the command is complete, the
71M6543F/H clears RCMD[4:2]. The command
code itself is in RCMD[4:2].
The 71M6543F/H 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 71M6543F/H 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.
