Bits 3 and 2: Selecting the Inputting Clock to the TMJ-2 (PS21 and PS20)
This bit works to select the clock to input to the TMJ-2. Selection of the leading edge or the
trailing edge is workable for counting by use of an external clock.

Notes: 1. The edge selection for the external clock inputs is made by setting the edge select
register (IEGR). See section 6.2.4, Edge Select Register (IEGR) for more information.
2. Don't care.

Bit 1: TMJ-2 Toggle Flag (TGL)
This flag indicates the toggled status of the underflowing with the TMJ-2. Reading only is
workable.
It will be cleared to 0 under the low power consumption mode.
Bit 1
TGL Description
0 The toggle output of the TMJ-2 is 0 (Initial value)
1 The toggle output of the TMJ-2 is 0
Bit 0: Switching Over Between Timer Output/Remote Controlling Output (T/R)
This bit works to select if using the timer outputs from the TMJ-1 as the output signal through
the TMO pin or if using the toggle outputs (remote controlled transmission data) from the TMJ-2
as the output signal through the TMO pin.
Bit 0
T/R Description
0 Timer outputs from the TMJ-1 (Initial value)
1 Toggle outputs from the TMJ-2 (remote controlled transmission data)
