Configuration Register
Use the configuration register to enter and exit shut-
down, check device type, and globally clear the digit
data (Tables 10
–
13). The S bit selects shutdown or nor-
mal operation (read/write). The D bit reports whether
the device is a MAX6958 or a MAX6959 (read only).
The R bit clears all the digit and segment data (data is
not stored-transient bit)
Scan-Limit Register
The scan-limit register sets the number of digits dis-
played, from one to four (Table 14). A bicolor digit is
connected as two monocolor digits. The scan-limit reg-
ister also limits the number of keys that can be
scanned. Since the number of scanned digits affects
the display brightness, the scan-limit register should
not be used to blank portions of the display (such as
leading zero suppression).
Intensity Register
An internal pulse-width modulator controlled by the
intensity register provides digital control of display
brightness. The modulator scales the average segment
current in 63 steps from a maximum of 63/64 down to
1/64 of the 23mA peak current. The minimum interdigit
blanking time is set to 1/64 of a cycle (Figure 11 and
Table 15).
