(2-4) Monitor mode

Monitor mode is used to monitor the data bus or pointers.

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

Next, when the IFCK signal is sent, data are output on the IFCK signal falling edge from the

MSB first. The data length is at its maximum (24 bits or three bytes) during monitoring of the

data bus. In cases where transfer must be interrupted, such as where only eight or 16 bits of the

MSB side are required, monitoring can be interrupted at any time by setting the CS signal to

High. When the CS signal goes High, the IFOK signal also goes High.

When CS = H, all monitor circuits are initialized.
