Note: When the internal microprocessor is running, GPO
(see CCR_FLT_FREQ in section 4.5.40).
In order to modify the GPO register, one must first change the Configuration Command Register
CCR_GPO at CCR address 0x20. After the CCR_GPO register is programmed, the exact same GPO
value must be programmed into the General Purpose Outputs register (see above).
Bit 0 of the GPO register is always reserved. When programming the CCR_GPO register it is ok to write
an 8-bit value. The system will ignore bit 0. When programming the General Purpose Outputs register
(see above), first read the register to get the current state of bit 0, change bits 1-7 as desired, then write
the new value into the register.

Description
General Purpose Output bits [7:0]. The General Purpose
Output bits control the GPO pins on the FS400. The FS403 has
all 8 GPO outputs available while the FS401 has only GPO
GPO
not necessarily the voltage level.
Reserved: Always set these bits to 0. Any other value will place
the FS400 into a manufacturing test mode.
