CY7C67200
Document #: 38-08014 Rev. *G Page 43 of 78
Register Description
The GPIO 0 Direction register controls the direction of the GPIO data pins (input/output). The GPIO 0 Direction register controls
GPIO15 to GPIO0 while the GPIO 1 Direction register controls GPIO31 to GPIO19.
When any bit of this register is set to ‘1’, the corresponding GPIO data pin becomes an output. When any bit of this register is
set to ‘0’, the corresponding GPIO data pin becomes an input.
Reserved
All reserved bits must be written as ‘0’.
GPIO 1 Direction Register [0xC028] [R/W]

Register Description
The GPIO 1 Direction register controls the direction of the GPIO data pins (input/output). The GPIO 0 Direction register controls
GPIO15 to GPIO0 while the GPIO 1 Direction register controls GPIO31 to GPIO19.
When any bit of this register is set to ‘1’, the corresponding GPIO data pin becomes an output. When any bit of this register is
set to ‘0’, the corresponding GPIO data pin becomes an input.
Reserved
All reserved bits must be written as ‘0’.
