SET CONTROL VREGEN
SET CONTROL VREGEN
is used to set the behavior of the internal software-controlled
regulator on the module. The PIO’s specified by the
PIO mask
parameter will be pulled
high by the regulator as specified by the
mode
parameter.
6.24.1
Syntax
Synopsis:
SET CONTROL VREGEN {
mode
} {
PIO mask
}
Description:
mode
0
Regulator is enabled on rising edge when its input voltage
(VREG_ENA) rises past around 1V and will hold the PIO’s high.
Warning:
using this mode may or may not, depending on your
setup, keep the module powered on until its power source is
disconnected or regulator mode is switched!
1
Regulator is enabled on rising edge (of VREG_ENA) and holds the
PIO voltage up until a falling edge is encountered, at which point
the regulator will pull the voltage down.
2
Regulator is enabled on rising edge and holds the voltage up
until another rising edge followed by a falling edge is
encountered, at which point the regulator will bring the voltage
down.
PIO mask
Bit mask used to specify which PIO’s are held up by the regulator. This
parameter is given in hexadecimal format.
Response:
SYNTAX ERROR
This event occurs if incorrect parameters are given.
