End flag

ESEL flag

function

Set the aperture mode for the aperture.

(1) Aperture mode

bit 7 6 5 4 3 2 1 0
    [] [] [-] [] [] [] [] []
     | | | | | | |
     | | | | | | + ---- 1: File number (FN) selection valid 1: Invalid | | | | | + ------- 1: Channel number (CN) selection valid 1: Invalid | | | | + ---------- 1: Submode (SM) selection enabled 1: Disabled | | | + ------------- 1: Coding information (CI) selection Enabled 1: Disabled | | + ---------------- 1: Invert subhead condition 1: Not | |
     | + ---------------------- 1: Frame address range valid 1: Invalid + ---------------- --------- 1: Initialize the aperture condition 1: Do not

(2) Inversion of subheader condition

If you invert the subheader condition, the output destination will be the opposite of the normal case for the subheader condition. That is, the sectors that match the subheader condition are output to the fake output connector, and the sectors that do not match are output to the true output connector.

1. Normal time

   ・ Output to true output connector	: The FAD range of the aperture matches [and] the subheader conditions match
   ・ Output to fake output connector	: The FAD range of the aperture does not match [or] The subheader condition does not match

2. At the time of reversal

   ・ Output to true output connector	: The FAD range of the aperture matches [and] the subheader conditions do not match
   ・ Output to fake output connector	: The FAD range of the aperture does not match [or] The subheader condition matches

(3) Initialization of aperture conditions

When the aperture condition is initialized, the other bit specifications are ignored and the following initial values are set.

-Frame address range	: Start FAD = 0, number of FAD sectors = 0
・ Subheader condition	: FN, CN, SMMSK, SMVAL, CIMSK, CIVAL all 0
・ Aperture mode	: All bits = 0

End flag

ESEL flag

function

Initializes the selector settings according to the value of the reset flag.

・ When reset flag = 0	: Erases all data in the specified buffer partition.
・ When the reset flag ≠ 0	: The buffer partition number is ignored.

(2) Initial value

Initialization sets the following initial values for all selectors.

-Buffer data	: All are erased. (All data in the CD buffer is erased.)
-Partition output connector	: All are disconnected.
・ Aperture conditions	: Same as initialization in aperture mode setting (CDC_SetFiltMode).
・ Aperture input connector	: All are disconnected.
・ True output connector	: Apertures with the same number and buffer partitions are connected.
