Transmit clock completion
detect time
Notes: 1. See figure 46.
2. See figure 47.
3. The transmit clock completion detect time is the high level period after 8 pulses of transmit
clocks are input. The serial interrupt request flag is not set if the next transmit clock is input
before the transmit clock completion detect time has passed.
4. The unit t
is applied when the MCU is in subactive mode. t

= 244.14
