Remark
(d) TMPn I/O control register 1 (TPnIOC1)
(e) TMPn I/O control register 2 (TPnIOC2)
(f) TMPn option register 0 (TPnOPT0)
(g) TMPn counter read buffer register (TPnCNT)
(h) TMPn capture/compare registers 0 and 1 (TPnCCR0 and TPnCCR1)
The value of the 16-bit counter can be read by reading the TPnCNT register.
These registers function as capture registers or compare registers depending on the setting of the
TPnOPT0.TPnCCSm bit.
When the registers function as capture registers, they store the count value of the 16-bit counter when
the valid edge input to the TIOPnm pin is detected.
When the registers function as compare registers and when D
INTTPnCCm signal is generated when the counter reaches (D
TIOPnm pin is inverted.
