Description
The GO bit can be written to at any time.
0
The VICDIV and VICCTL registers can be written to without
affecting the operation of the VIC port. All the logic in the VIC
port is held in reset state and a 0 is output on the VCTL output
line. A write to VICCTL bits as well as setting GO to 1 is allowed
in a single write operation. The VICCTL bits change and the GO
bit is set, disallowing any further changes to the VICCTL and
VICDIV registers.
1
The VICDIV and VICCTL (except for the GO bit) registers
cannot be written. If a write is performed to the VICDIV or
VICCTL registers when the GO bit is set, the values of these
registers remain unchanged. If a write is performed that clears
the GO bit to 0 and changes the values of other VICCTL bits, it
results in GO = 0 while keeping the rest of the VICCTL bits
unchanged. The VIC port is in its normal working mode in this
state.
