Timer output data
Timer output data is "0"
Timer output data is "1"
fX/22 (1.25 MHz)
fX/26 (78.1 kHz)
fX/27 (39.1 kHz)
fXT
(32.768 kHz)
Note
Bit 7 is read-only.
Caution
Disable interrupts in advance by using the interrupt mask flag register (MK1) to change
the data of TCL901 and TCL900. Also, prevent the timer output data from being inverted
by setting TOC90 to1.
Remarks 1. fX:
Main system clock oscillation frequency
2. fXT:
Subsystem clock oscillation frequency
3. The parenthesized values apply to operation at fX = 5.0 MHz or fXT = 32.768 kHz.
