(8) TAAn option register 1 (TAAnOPT1)

The TAAnOPT1 register is an 8-bit register that controls the 32-bit capture function realized by a cascade

connection.

Rewriting this register is prohibited while the timer is operating (TAAnCTL0.TAAnCE = 1).

This register can be read or written in 8-bit or 1-bit units.

Reset sets this register to 00H.

Cautions 1. Cascade connection and timer-tuned operation cannot be

used together. Be sure to set TAAnCTL1.TAAnSYE to 0 for

a cascade connection.

2. For a cascade connection, set the free-running timer

mode and use the TAAnCCR0 and TAAnCCR1 registers as

capture registers.

For details of cascade connection, see 7.8 Cascade

Connection.
