EX_STARTn/EX33_STARTn
EX_STARTn starts writing when an external falling edge is detected on EX_STARTn instead of the PROGRAM switch.
To use this function, it must be set in C-Flash (see below).
Please note that edge detection of EX_STARTn signal will be ignored when Write operation is in progress.
EX_BSY/EX33_BSY
To use EX_BSY, it needs to be configured using C-Flash. (see below)。
When EX_BSY is configured, H is output during Write operation and L is output when Write operation completes.
Please note that this signal is shared with the JTAG’s
TRST signal. Make sure not use this signal when the TRST
signal of the CPU on the target system is connected to FP.
EX_NG
To use EX_NG, it needs to be configured using C-Flash. (see below)。
When EX_NG is configured, H is output when Write operation fails.
Please note that this signal is shared with the JTAG’s TDI signal. Make sure not use this signal when the TDI signal of
the CPU on the target system is connected to FP.
In External input/output function using 3.3V I/F, no signal is output.
