I/O RAM Description – Alphabetical Order
The following conventions apply to the descriptions in this table:
Bits marked with an asterisk (e.g. DIO_DIR1[4] ) are applicable to the 71M6534 only.

Bits with a W (write) direction are written by the MPU into configuration RAM. Typically, they are initially stored in flash memory and copied to
the configuration RAM by the MPU. Some of the more frequently programmed bits are mapped to the MPU SFR memory space. The remaining
bits are mapped to 2xxx.
Bits with an R (read) direction can be read by the MPU.
Columns labeled Reset and Wake describe the bit values upon reset and wake, respectively. “NV” in the Wake column means the bit is powered
by the nonvolatile supply and is not initialized. LCD-related registers labeled “L” retain data upon transition from LCD mode to BROWNOUT
mode and vice versa, but do not retain data in SLEEP mode. “–“ means that the value is undefined.
Write-only bits will return zero when they are read.

Description
Enables ADC and VREF. When disabled, removes bias current.
Battery Measure Enable. When set, a load current is immediately applied to the battery
and it is connected to the ADC to be measured on Alternative Mux Cycles. See the
MUX_ALT bit.

CE clock select. When set, the CE is clocked at 10 MHz. Otherwise, the CE clock
frequency is 5 MHz.

00 = toggle, except at the mux sync edge at the end of SUMCYCLE, an alternative
MUX frame is automatically inserted at the end of each accumulation interval.
01 = positive.
10 = reversed.
11 = toggle, no alternative MUX frame is inserted
When CHOP_I_EN is set, chop mode for the analog current inputs can be enabled
with the CHOP_IA, CHOP_IB, CHOP_IC, and CHOP_ID bits.
When CHOP_I_EN is set, these bits enable chop mode for the respective channel.
