8-bit Timer with External Trigger (TIMB)
ST7FLCD1
82/95
Bit 4 = OVFE
Timer Overflow Interrupt Enable
This bit is set and cleared by software.
0
Interrupt disabled
1
Interrupt enabled
Bit 3 = TAR
Timer Auto Reload
This bit is set and cleared by software.
0
One-shot mode. The counter restarts after writing to the TIMCPRB register.
1
Auto reload mode. The counter is reloaded automatically from the TIMCPRB register when 00h
is reached.
Bit 2 = EXT
External Trigger
This bit is set and cleared by software.
0
Internal. The downcounter restarts after writing to the TIMCPRB register or after an auto-reload
if the TAR bit is set
1
External. The downcounter is preloaded with the TIMCPRB register but the countdown starts
only when the external signal is detected, not by writng to the TIMCPRB register.
Bit 1 = EDG
External Signal Edge
This bit is set and cleared by software.
0
A rising edge signal starts the count-down.
1
A falling edge signal starts the count-down
Bit 0 = EEF
External Event Flag
This bit is set and cleared by hardware when an external event occurs.
This bit is cleared when the counter reaches “00h” in External mode or when the value of the EXT
bit is changed by software.
In Internal mode, this bit is set when the selected edge is detected (the EDG bit) but it is never
cleared by itself. It may then be used as a simple edge detector.
TIMER B COUNTER PRELOAD REGISTER (TIMCPRB)
Read/Write
Reset value: (01h)
Bits [7:0] = PR[7:0]
Counter Preload Data
This bit is set and cleared by software.
Bits hold the reload value which is loaded in the counter either immediately (EXT = 0) or when the
external signal is detected (EXT = 1).
Note:
The N number loaded in TIMCPRB register corresponds to a time of (N + 1) x Period timer.
The "00" value is prohibited.
