9.3 Registers to Control 8-Bit Timer/Event Counters 50, 51
(1) Timer clock select register 5n (TCL5n: n = 0, 1)
220
The following four types of registers are used to control 8-bit timer/event counters 50, 51.
• Timer clock select register 5n (TCL5n)
• 8-bit timer mode control register 5n (TMC5n)
• Port mode register 7 (PM7)
• Port 7 (P7)
Remark n = 0, 1
Address: FF71H
Symbol
TCL50
This register sets the count clock of 8-bit timer/event counter 5n and the valid edge of TI50, TI51 input.
TCL5n is set by an 8-bit memory manipulation instruction.
RESET input clears TCL5n to 00H.
Note Expanded-specification products of PD780024A, 780034A Subseries only.
Cautions 1. When rewriting TCL50 to other data, stop the timer operation beforehand.
Remarks 1. When cascade connection is used, only TCL50 is valid for count clock setting.
2. f
2. Be sure to clear bits 3 to 7 to 0.
