Three clocking outputs PE0, PE1 and PE2 are supported by
the ST2202. These signals are very useful for outputs of high
frequency, such as PWM base signal or carrier of remote
Clocking Outputs: PE0 and PE1
Overflow states of Timers will be connected to toggle data of
PE[0:1]
when setting function selection bits
TCO0/TCO1
(
PMCR[0:1]
). Meanwhile PE0/PE1 output clocked data of half
the frequency of Timers. After resetting
TCO0/TCO1
, the toggle
operation ceases. Then PE0/PE1 return to the original logic
level of
PE[0:1]
.
control. Timer0, Timer1 overflow signals are clock sources for
PE0 and PE1, while BGRCK are for PE2.
BGRCK will output through PE2 when setting function selection
bit
BCO
(
PMCR[2]
). If
BCO
is cleared, PE2 returns to the
original logic level of
PE[2]
.
Summary of clocking outputs registers is shown in TABLE 13-1.
The clocking outputs enable bits can be found in TABLE 13-2.
