Address: FF79H
Symbol
TCL51
Note Expanded-specification products of PD780024A, 780034A Subseries only.
Cautions 1. When rewriting TCL51 to other data, stop the timer operation beforehand.
Remarks 1. When cascade connection is used, only TCL50 is valid for count clock setting.
<1> 8-bit timer counter 5n (TM5n) count operation control
<2> 8-bit timer counter 5n (TM5n) operating mode selection
<3> Discrete mode/cascade connection mode selection (TMC51 only)
<4> Timer output F/F (flip-flop) status setting
<5> Active level selection in timer F/F control or PWM (free-running) mode.
<6> Timer output control
TMC5n is a register that makes the following six settings.
TMC5n is set by a 1-bit or 8-bit memory manipulation instruction.
RESET input clears TMC5n to 00H.
