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.

Bit 7

HOE

Description

The P44/TMO1/HIRQ1/HSYNCO pin functions as the P44/TMO1/HIRQ1 pin

(Initial value)

The P44/TMO1/HIRQ1/HSYNCO pin functions as the HSYNCO pin

Bit 6

VOE

Description

The P61/FTOA/

KIN1/CIN1/VSYNCO pin functions as the P61/FTOA/ KIN1/CIN1 pin

(Initial value)

The P61/FTOA/

KIN1/CIN1/VSYNCO pin functions as the VSYNCO pin
