(11) TAAn counter read buffer register (TAAnCNT)
The TAAnCNT register is a read buffer register that can read the count value of the 16-bit counter.
If this register is read when the TAAnCTL0.TAAnCE 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 TAAnCNT register is cleared to 0000H when the TAAnCE bit = 0. If the TAAnCNT register is read
at this time, the value of the 16-bit counter (FFFFH) is not read, but 0000H is read.
Reset clears the TAAnCE bit to 0. Therefore, the value of the TAAnCNT register is cleared to 0000H.
Caution Accessing the TAAnCNT register is prohibited in the following statuses. For details, see 3.4.9 (2)
Accessing specific on-chip peripheral I/O registers.
• When the CPU operates with the subclock and the main clock oscillation is stopped
• When the CPU operates with the internal oscillation clock
