Description
8-bit Single-chip Microcontrollers
Manufacturer
Renesas Electronics Corporation.
Datasheet
(2) 8-bit timer mode control register 50 (TMC50)
Note Bits 2 and 3 are write-only.
(Refer to Cautions and Remarks on the next page.)
TMC50 is a register that performs the following five types of settings.
<1> 8-bit timer counter 50 (TM50) count operation control
<2> 8-bit timer counter 50 (TM50) operating mode selection
<3> Timer output F/F (flip-flop) status setting
<4> Active level selection in timer F/F control or PWM (free-running) mode
<5> Timer output control
TMC50 can be set by a 1-bit or 8-bit memory manipulation instruction.
RESET input clears this register to 00H.
Figure 7-5 shows the TMC50 format.
