TC77
4.0
INTERNAL REGISTER
STRUCTURE
The TC77 Internal register structure consists of three
registers. The Temperature and Manufacturer’s Identi-
fication registers are read only, while the Configuration
register is write only.
TABLE 4-1:
REGISTERS FOR TC77
4.1
Configuration Register (CONFIG)
The Configuration register is write only. This register
selects either Shutdown, Continuous Conversion or
Test modes:
C15:C0 =
XXXX/XXXX 1111/1111
(Shutdown
mode)
C15:C0 =
XXXX/XXXX 0000/0000
(Continuous
Conversion mode)
The TC77 is in Shutdown mode when bits C0 to
C7 are all equal to ‘
1
’s. The TC77 will be in the
Continuous Conversion mode if a ‘
0
’ in any bit
location from C0 to C7 is written to the Configura-
tion register. The TC77 is in the Continuous
Conversion mode at power-up.
It is recommended that the user write all ‘
0
’s or all ‘
1
’s
to the Configuration register because other bit codes
may put the TC77 in a test mode used for calibration
and production verification tests. Section 3.3 lists the
Configuration register bit codes that can be written to
the TC77 without having the device enter a production
test mode.
During Shutdown mode, the serial bus is still active.
The current consumption of the TC77 will be less than
1 μA during the time between serial communication.
4.2
Temperature Register (TEMP)
The Temperature register is read only and holds the
temperature conversion data. Bits 0 and 1 are unde-
fined and will be tri-state outputs during a read
sequence. Bit 2 is set to a logic ‘
1
’ after completion of
the first temperature conversion following a power-up
or reset event. Bit 2 is set to a logic ‘
0
’ during the time
needed to complete the first temperature conversion.
Therefore, the status of bit 2 can be monitored to indi-
cate that the TC77 has completed the first temperature
conversion. Bits 15:3 contain the 13 bit two’s comple-
ment data from the temperature conversion.
4.3
Manufacturer’s ID Register (M_ID)
The Manufacturer’s Identification code is contained in
this read only register. The Manufacturer ID register is
only available for a read operation when the TC77 is in
Shutdown mode. The Manufacturer’s ID code is con-
tained in bits 15:8 and is equal to 54 hex to indicate a
Microchip device. Bits 1:0 are undefined and will be tri-
state outputs during a read sequence, while bits 7:2 are
set to ‘
0
’.
