LEVEL1
When the GPIO1 pin is defined as output, this bit determines the output level on GPIO1 and can be read and written.
0: Output low level.
1: Output high level. (default)
When the GPIO1 pin is defined as input, this bit indicates the input level on GPIO1 and can only be read.
0: Input low level.
1: Input high level. (default)
2
LEVEL0
When the GPIO0 pin is defined as output, this bit determines the output level on GPIO0 and can be read and written.
0: Output low level.
1: Output high level.
When the GPIO0 pin is defined as input, this bit indicates the input level on GPIO0 and can only be read.
0: Input low level.

CLKE1_EN
This bit controls whether the output on the CLKE1 pin is enabled.
0: The output is disabled. CLKE1 is in High-Z state.
1: The output is enabled. The frequency of CLKE1 is determined by the CLKE1 bit (b2, CLKG). (default)
2
CLKE1
This bit is valid only when the CLKE1_EN bit (b3, CLKG) is ‘1’. This bit selects the clock frequency output on the CLKE1 pin.
0: 8 KHz.
1: 2.048 MHz. (default)
