Port Strobe.
Strobe the port_matrix and port_roff bits values from this register to the GPIO pads.
The operation requires additional 2 CPU clock to finish after writing 0->1->0 to this bit.
When 1 is written to this bit the GPIO latches open and the values of port_matrix and
port_off are propagated to GPIO pads. Software must clear this bit to capture those
two bits in the GPIO pads internal HV permanent latches.
Port Roff Mode.
Roff mode, read from this bit returns the actual Roff mode value as reported from
GPIO pad. When a 1 is latched into the GPIO pad internal Roff mode HV latch then
the GPIO Roff mode gets invoked. The GPIO[1:2] will have their pull-up resistors
turned off.
Port Matrix Mode.
Matrix mode, read from this bit returns the actual value matrix mode value as
reported from GPIO pad. When a 1 is latched into the GPIO pad internal matrix mode
HV latch then the GPIO matrix mode gets invoked. The GPIO[1:3] are driven low with
resistor pull-ups disabled. This is intended for matrix button mode to wake up from
sleep mode.
Increase Drive Strength by 2x on All Outputs.
Input GPIO[5] pin trip point set to 45% VDD.
Input GPIO Pin Trip Point Set to 45% VDD (except GPIO[5])
LED Current Drive Strength.
It must be set to non-zero value for LED to have any current. This is just a current
source setting. The actual turning of the LED on and off is controlled by the GPIO[5]
output bit in P0.
00: LED off
01: LED current = 0.62*600uA
10: LED current = 1.00*600uA
11: LED current = 1.62*600uA
