The following table shows the functions of the capture/compare register in each operation mode, and how to
write data to the compare register.
The TQ0CNT register is a read buffer register from which the value of the 16-bit counter can be read.
If this register is read when the TQ0CTL0.TQ0CE bit = 1, the count value of the 16-bit timer can be read.
This register is read-only, in 16-bit units.
The value of the TQ0CNT register is cleared to 0000H when the TQ0CE bit = 0. If the TQ0CNT register is read
at this time, the value of the 16-bit counter (FFFFH) is not read, but 0000H is read.
Because the TQ0CE bit is cleared to 0, the value of the TQ0CNT register is cleared to 0000H after reset.
Caution Accessing the TQ0CNT register is prohibited in the following statuses. Moreover, if the
TQ0CNT

Operation Mode
system is in the wait status, the only way to cancel the wait status is to execute a reset. For
details, see 3.4.9 (1) Accessing specific on-chip peripheral I/O registers.
• When the CPU is operating on the subclock and main clock oscillation is stopped
• When the CPU is operating on the internal clock
After reset: 0000H
