[FLDC Mode Register] FLDM
The FLDC mode register is a 8-bit register respectively which is used
to control the FLD automatic display and to set the blanking time
Tscan for key-scan.
Fig. 43 Structure of FLDC mode register
FLDC mode register
(FLDM: address 0EF416)
Automatic display control bit (P0, P1, P2, P3, P8)
0 : General-purpose mode
1 : Automatic display mode
Display start bit
0 : Stop display
1 : Display
(start to display by switching “0” to “1”)
Tscan control bits
00 : FLD digit interrupt (at rising edge of each digit)
01 : 1 ! Tdisp
10 : 2 ! Tdisp
11 : 3 ! Tdisp
Timing number control bit
0 : 16 timing mode
1 : 32 timing mode
Gradation display mode selection control bit
0 : Not selecting
1 : Selecting (Note 1)
Tdisp counter count source selection bit
0 : f(XIN)/16 or f(XCIN)/32
1 : f(XIN)/64 or f(XCIN)/128
High-breakdown voltage port drivability selection bit
0 : Drivability strong
1 : Drivability weak
b7
b0
FLD blanking interrupt
(at falling edge of the last digit)
Notes 1: When a gradation display mode is selected, a number of timing is max. 16
timing. (Set the timing number control bit to “0”.)
2: When changing bit 4 (timing number control bit) or bit 5 (gradation display
mode selection control bit), set “0” to bit 1 (display start bit) to perform at
display stop state.
