Section 14 Timer Array Unit J (TAUJ)
14.8 Channel Output Modes
The output of the TAUJnTTOUTm pin can be controlled in two ways, the latter
of which can be further split into individual modes.
• Control by software (TAUJnTOE.TAUJnTOEm = 0)
When controlled by software, the value written in the output register bit
(TAUJnTO.TAUJnTOm) is output through the output pin (TAUJnTTOUTm).
• Control by TAUJ signals (TAUJnTOE.TAUJnTOEm = 1)
When controlled by TAUJ signals, the output level of TAUJnTTOUTm is set
or reset or toggled by internal signals. The value of TAUJnTO.TAUJnTOm is
updated accordingly to reflect the value of TAUJnTTOUTm.
– Independent control (TAUJnTOM.TAUJnTOMm = 0)
In independent operation, the output of the TAUJnTTOUTm pin is only
affected by settings of channel m. Therefore, independent channel
operation should be selected (TAUJnTOM.TAUJnTOMm = 0).
– Synchronous control (TAUJnTOM.TAUJnTOMm = 1)
In synchronous operation, the output of the TAUJnTTOUTm pin is
affected by settings of channel m and those of other channels. Therefore,
synchronous channel operation should be selected for all synchronizing
channels (TAUJnTOM.TAUJnTOMm = 1).
The TAUJnTO.TAUJnTOm bit can always be read to determine the current
value of TAUJnTTOUTm, regardless of whether the pin is controlled by
software or operated independently or synchronously.
Control bits
The settings of the control bits required to select a specific channel output
mode are listed in Table 14-8, Channel Output Modes.
The channel output modes are described in detail in:
• Section 14.8.2, Channel Output Modes Controlled Independently by TAUJn
• Section 14.8.3, Channel Output Modes Controlled Synchronously by TAUJn
Batch operation of
TAUJnTOm bit
The TAUJnTOE.TAUJnTOEm bit is used to control whether settings are to be
reflected to the TAUJnTOm bit or not.
During the write operation to the TAUJnTO register, the setting of TAUJnTOm
is written only to the bit (channel) for which TAUJnTOE.TAUJnTOEm = 0 is set.
To the bit (channel) for which TAUJnTOE.TAUJnTOEm = 1 is set, the setting of
TAUJnTOm is not reflected.
Note
The TAUJnTO.TAUJnTOm bit is assigned so that the bit number corresponds
to the channel number.
