SPI_CRC_DAT: CRC Data
(Address 0x1D )
Bit
Bit Symbol
Bit Description
[7:0] CRC_DAT
CRC Data
When written, this register reset CRC:
Any Value:
Reset CRC
When read, this register indicates the CRC data.
18.8 GPIO REGISTERS
GPIO_DIRCN: GPIO Direction
(Address 0x0E )
Bit
Bit Symbol
Bit Description

GPIO_DIRCNx
GPIO direction control – these bits are used to control the direction of each General Purpose
Input/Outputs (GPIO) pins D0 - D6.
0 (default):
Dx is an Input
1:
Dx is an Output
where 0
≤ x ≤ 6.
For example, writing a 1 to bit 6 means D6 is an Output.
Note: If D6 is used for DRDYB, then it cannot be used for GPIO.
GPIO_DAT: GPIO Data
(Address 0x0F)
Bit
Bit Symbol
Bit Description

Reserved

x
Dx
Write Only - when GPIO_DIRCNx = 0
0: Dx is LO
1: Dx is HI
Read Only - when GPIO_DIRCNx = 1
0: Dx driven LO
1: Dx driven HI
where 0
≤ x ≤ 6.
For example, writing a 0 to bit 4 means D4 is LO.
It is okay to Read the GPIOs that are configured as outputs and write to GPIOs that are
configured as inputs. Reading the GPIOs that are outputs would return the current value
on those GPIOs, and writing to the GPIOs that are inputs are neglected.
