RL78/G1A CHAPTER 6 TIMER ARRAY UNIT

6.3.11 Timer output level register m (TOLm)
The TOLm register is a register that controls the timer output level of each channel.
The setting of the inverted output of channel n by this register is reflected at the timing of set or reset of the timer output
signal while the timer output is enabled (TOEmn = 1) in the Slave channel output mode (TOMmn = 1). In the master
channel output mode (TOMmn = 0), this register setting is invalid.
The TOLm register can be set by a 16-bit memory manipulation instruction.
The lower 8 bits of the TOLm register can be set with an 8-bit memory manipulation instruction with TOLmL.
Reset signal generation clears this register to 0000H.

Control of timer output level of channel n
0 Positive logic output (active-high)
1 Negative logic output (active-low)
Caution Be sure to clear bits 15 to 8, and 0 to “0”.
Remarks 1. If the value of this register is rewritten during timer operation, the timer output logic is inverted when
the timer output signal changes next, instead of immediately after the register value is rewritten.
2. m: Unit number (m = 0), n: Channel number (n = 0 to 7 (however, timer input pin (TImn), timer
output pin (TOmn) : n = 0, 1, 3 to 7))
