SIO_B
14 and
13
RW
Synchronization port_B conguration:
00: HS_B and VS_B are input (i.e. 3-state)
01: HS_B is output, HGT of HPS; VS_B is output, VGT of HPS
10: HS_B is output, RESET signal for a field memory; VS_B is input, vertical
sync signal for BRS this setting is needed for the field memory mode
11: HS_B is output, HGT of BRS; VS_B is output, VGT of BRS

SYNC_B
10 to 8
RW
Sync edge selection and eld detection mode internal sync signals SyncB
(Hb, Vb and Fb) if:
HS, VS are input: Hb/Vb/Fb derived from pins
HS, VS are output: HS/VS as select by SIO_B
000: Hb at rising edge of HS; Vb at rising edge of VS; Fb = HS
× VS-rising,
directly
001: Hb at rising edge of HS; Vb at falling edge of VS; Fb = Hs
× VS-falling,
directly
010: Hb at rising edge of HS; Vb at rising edge of VS; Fb = HS
× VS-falling,
forced toggle
011: Hb at rising edge of HS; Vb at falling edge of VS; Fb = HS
× VS-falling,
forced toggle
100: Hb at rising edge of HS; Vb at rising edge of VS
101: Hb at rising edge of HS; Vb at falling edge of VS; Fb = free toggle
110: Hb at rising edge of HS; Vb at rising and falling edge of Frame Sync at
the VS pin; Fb = direct FS
111: Hb, Vb and Fb derived from SAV and EAV decoded from the
data-stream at D1_B port. Not used if the MSB of HPSdatasel in Table 71
is set to logic 1
