Bit Description
CRC Data
When written, this register reset CRC:
Any Value: Reset CRC
When read, this register indicates the CRC data.
Bit Description
-
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
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.
Bit Description
-
Write Only - when GPIO_DIRCN = 0
0: Dx is LO
1: Dx is HI
Read Only - when GPIO_DIRCN = 1
0: Dx driven LO
1: Dx driven HI
where 0
For example, writing a 0 to bit 4 means D4 is LO.
