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

Description
ADC_E
2005[3]
0
R/W
Enables ADC and VREF. When disabled, removes bias current.
BME
2020[6]
0
–
R/W
Battery Measure Enable. When set, a load current is immediately applied to the bat-
tery and it is connected to the ADC to be measured on Alternative Mux Cycles. See
the MUX_ALT bit.
BOOT_SIZE[7:0]
20A7[7:0]
01
R/W
End of space reserved for boot program. The ending address of the boot region is
1024*BOOT_SIZE.
CE10MHZ
2000[3]
0
R/W
CE clock select. When set, the CE is clocked at 10 MHz. Otherwise, the CE clock
frequency is 5 MHz.
CE_E
2000[4]
0
R/W
CE enable.
CE_LCTN[7:0]
20A8[7:0]
0x31
R/W
CE program location. The starting address for the CE program is 1024*CE_LCTN.
CHOP_E[1:0]
2002[5:4]
00
R/W
Chop enable for the reference bandgap circuit. The value of CHOP will change on the
rising edge of MUXSYNC according to the value in CHOP_E:
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
CHOP_I_EN
20AB[0]
0
R/W
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.
CHOP_IA
CHOP_IB
CHOP_IC
CHOP_ID
20AC[0]
20AC[4]
20AD[0]
20AD[4]
0
R/W
When CHOP_I_EN is set, these bits enable chop mode for the respective channel.
