The slice line setting registers 1 to 4 (SLINE1 to SLINE4) specify slice fields and lines. Up to four
slice lines can be specified; these are specified in the slice line setting registers 1 to 4 respectively.
These are 8-bit read/write registers. Rewrites of SLINE should be performed after an even (odd)
field slice completion interrupt is output, or after module stop mode has been set, registers have
been initialized, and module stop mode has been cleared again. If SLINE is rewritten during a data
slice operation, a malfunction will result; do not perform rewriting during data slice operation.
When reset, when the module is stopped, in sleep mode, in standby mode, in watch mode, in
subactive mode, or in subsleep mode, the registers are initialized to H'20.
Bit 7
Slice Enable Bit (SENBLn n=1 to 4): Enables or disables data slice operations for the
line specified by SFLDn and SLINEn4 to SLINEn1.
When data slicing for a given line is completed, this bit is reset to 0, and slicing is not again
performed until it is set to 1. This bit is set at the rising edge of the Vsync signal; hence data
slicing settings become valid from the rising edge of the next Vsync signal after this bit has been
set. When 1 is written to this bit, the corresponding slice detection register is cleared, and so
caution should be exercised.
Bit 7
SENBLn
Description
0
When read: Disables data slice operation for the specified lines
[Clearing condition]
When the data slice operation for the line has been completed
1
Enables data slice operation for the specified lines
Bit 6
Field Setting Bit (SFLDn n=1 to 4): Specifies the field of the slice line. For information
on field discrimination, refer to section 27.2.6, Field Detection Window Register (FWIDR).
