13.2.2
TCONRO is an 8-bit readable/writable register that controls output signal output, phase inversion,
etc.
TCONRO is initialized to H'00 by a reset and in hardware standby mode.
Bits 7 and 4—Output Enable (HOE, VOE, CLOE, CBOE): These bits control
enabling/disabling of horizontal synchronization signal (HSYNCO), vertical synchronization
signal (VSYNCO), clamp waveform (CLAMPO), and blanking waveform (CBLANK) output.
When output is disabled, the state of the relevant pin is determined by the port DR and DDR, FRT,
TMR, and PWM settings.
Output enabling/disabling control does not affect the port, FRT, or TMR input functions, but some
FRT and TMR input signal sources are determined by the SCONE bit in TCONRI.
