Description
The timer does not reach its end-of-count value. This bit is reset
to 0 every time the TMRx_CTL register is read.
The timer reaches its end-of-count value. If IRQ_EN is set to 1,
an interrupt signal is sent to the CPU. This bit remains 1 until the
TMRx_CTL register is read.
Timer interrupt requests are disabled.
Timer interrupt requests are enabled.
Reserved.
The timer operates in SINGLE PASS mode. PRT_EN (bit 0) is
reset to 0, and counting stops when the end-of-count value is
reached.
The timer operates in CONTINUOUS mode. The timer reload
value is written to the counter when the end-of-count value is
reached.
Clock ÷ 4 is the timer input source.
Clock ÷ 16 is the timer input source.
Clock ÷ 64 is the timer input source.
Clock ÷ 256 is the timer input source.
The reload and restart function is disabled.
The reload and restart function is enabled. When a 1 is written to
this bit, the values in the reload registers are loaded into the
downcounter when the timer restarts. The programmer must
ensure that this bit is set to 1 each time SINGLE-PASS mode is
used.
The programmable reload timer is disabled.
The programmable reload timer is enabled.
