One-shot signal output
One-shot signals can be output from "SHT0", "SHT1" and "BCST" pins.
These one-shot signals can be used for such as start signals for CPU peripherals.
6.4.1
'General-purpose one-shot 0' signal (SHT0 pin)
"General-purpose one-shot 0" signal can be output from "SHT0" pin by writing "Operation Command" from "Local CPU" or
trigger signal input from "General-purpose input" pin.
"Delay time" (RSH0), "Pulse width" (RSHS.SHW0) and "Output logic" (RSHS.SHL0) can be set for "General-purpose one-shot
0" signal.
Item
Description
RSH0
Set the delay time until "General-purpose one-shot 0" signal is output.
"0" to "65535" can be set.
The output delay time is "(RSH0 - 1) × 100 μs".
There is an error that is up to 100μs.
When "RSH0 = 0" is set, no pulse is output.
RSHS.SHW0
Set the pulse width of "General-purpose one-shot 0" signal (SHT0 pin).
"0" to "127" can be set.
The pulse width is "RSHS.SHW0 × 100 μs".
When "RSHS.SHW0 = 0" is set, no pulse is output.
RSHS.SHL0
Select the output logic of "General-purpose one-shot 0" signal (SHT0 pin).
0: Normally, by "H level", outputs negative logic pulse by trigger.
1: Normally, by "L level", outputs positive logic pulse by trigger.
6.4.1.1
'SHT0' signal output by operation command
When "RENV2.TS0 = 00b" is set, a "General-purpose one-shot 0" signal can be output when writing the "CST0" (30h) operation
command.
The "General-purpose one-shot 0" signal is output from the "SHT0" pin according to the settings of the "RSH0" (0Ch) register
and the "RSHS" (10h) register.
