... There are two further modes: a mode where the data bus or pointer (s) is monitored at a preset program counter (PC) and a mode where a loop counter (LC) is added to monitor conditions in addition to the PC. After the command is issued, when the TC9447F loads data to the IFDO register (IFDOR), the IFOK pin signal is set to Low (see (1) above). ...

There are two further modes: a mode where the data bus or pointer (s) is monitored at a preset program counter (PC) and a mode where a loop counter (LC) is added to monitor conditions in addition to the PC. First, issue the monitoring command, which has no data. When the TC9447F loads data to the IFDO register (IFDOR), the IFOK pin signal is set to Low (see (1) above). 2 Next, the I C read command (ID = 33h) is issued, then when the IFCK signal is sent, the data are output on the IFCK signal falling edge starting from the MSB ...

... When using a command to control the DF block mute on/off (CMD: 36h, bit 5), the mute end flag is output from the IFOK pin after the mute operation completes. Example: Note 1: At power on, the IFOK pin output is undefined. When the CS signal goes Low, the IFOK signal goes High. 16 TC9447F 2002-02-05 ...

... Self-boot function description (1) Self-boot function The TC9447F supports a self-boot function for setting coefficients and offsets. As Figure 1 shows, the data are set via the microcontroller interface circuit. First saving the data to be set via the microcontroller in the self-boot ROM (SBROM) allows various modes to be set later ...
