TTL OUTPUT
1,2,3,4 丝印正确，正常输出
SIGNAL_GENERATOR
启动方式:
1.寄存器控制启动
2.外部触发启动
3.TIMECODE触发启动
帧格式:
TIMECODE:
25/30/...
GENLOCK:
....
产生:
1.start_state_sig (高电平表示拍照进行中)
2.timecode_sig[64]
3.timecode_tirgger_sig[1]
4.genlock_sig[1] 帧信号,场信号
5.秒信号
TTL_INPUT

TIMECODE_OUTPUT
GENLOCK_INPUT
1. 修改启动方式
2. 修改TIMECODE启动时间戳
// timeocde[0->63]
// 0 1 2 3 4 5 6 7
// 帧秒分时 U0U1U2U3
