Bit
Description
31 to 29
Reserved. These bits are reserved and should be written as 0 by user code.
28
Reserved. This bit is reserved and should be written as 1 by user code.
27 to 25
Reserved. These bits are reserved and should be written as 0 by user code.
24
Internal P0.6 enable bit. This bit must be set to 1 by user software before the HVCON and HVDAT MMRs can be used to
indirectly access the high voltage serial interface.
23 to 21
Reserved. These bits are reserved and should be written as 0 by user code.
20
Internal P0.5 enable bit. This bit must be set to 1 by user software before the HVCON and HVDAT MMRs can be used to
indirectly access the high voltage serial interface.
19 to 17
Reserved. These bits are reserved and should be written as 0 by user code.
16
GPIO_4 function select bit.
Set to 1 by user code to configure the GPIO_4 pin as ECLK, enabling a 2.56 MHz clock output on this pin.
Cleared by user code to 0 to configure the GPIO_4 pin as a general-purpose I/O (GPIO) pin.
15 to 13
Reserved. These bits are reserved and should be written as 0 by user code.
12
GPIO_3 function select bit.
Set to 1 by user code to configure the GPIO_3 pin as MOSI (master output, slave input) data for the SPI port.
Cleared by user code to 0 to configure the GPIO_3 pin as a general-purpose I/O (GPIO) pin.
11 to 9
Reserved. These bits are reserved and should be written as 0 by user code.
8
GPIO_2 Function Select Bit.
Set to 1 by user code to configure the GPIO_2 pin as MISO (master input, slave output) data for the SPI port.
Cleared to 0 by user code to configure the GPIO_2 pin as a general-purpose I/O (GPIO) pin.
7 to 5
Reserved. These bits are reserved and should be written as 0 by user code.
4
GPIO_1 function select bit.
Set to 1 by user code to configure the GPIO_1 pin as SCLK I/O for the SPI port.
Cleared to 0 by user code to configure the GPIO_1 pin as a general-purpose I/O (GPIO) pin.
3 to 1
Reserved. These bits are reserved and should be written as 0 by user code.
0
GPIO_0 function select bit.
Set to 1 by user code to configure the GPIO_0 pin as SS I/O for the SPI port.
Cleared to 0 by user code to configure the GPIO_0 pin as a general-purpose I/O (GPIO) pin.
