Always 0. No corresponding GPIO.
GP_IO_SEL2[49:48, 39:32] — R/W.
0 = GPIO signal is programmed as an output.
1 = Corresponding GPIO signal (if enabled in the GPIO_USE_SEL2 register) is
This register corresponds to GPIO[55:48, 43:32]. Bit 0 corresponds to GPIO32.
Reserved. Read-only 0
GP_LVL[49:48, 39:32] — R/W.
If GPIO[n] is programmed to be an output (via the corresponding bit in the GP_IO_SEL
register), then the corresponding GP_LVL[n] bit can be updated by software to drive a
high or low value on the output pin. 1 = high, 0 = low.
If GPIO[n] is programmed as an input, then the corresponding GP_LVL bit reflects the
state of the input signal (1 = high, 0 = low.) and writes will have no effect.
When configured in native mode (GPIO_USE_SEL[n] is 0), writes to these bits have no
effect. The value reported in this register is undefined when programmed as native
mode.
This register corresponds to GPIO[55:48, 43:32]. Bit 0 corresponds to GPIO32.
