8-BIT TIMER AND REMOTE CONTROLLER CARRIER GENERATOR CIRCUIT
The 8-bit timer is mainly used to generate the leader pulse of the remote controller signal, and to output codes.
Operations of timers are controlled by the GET instruction, the PUT instruction, and registers on the register file.
7.1
CONFIGURATION OF THE 8-BIT TIMER (WITH MODULO FUNCTION)
Figure 7-1 shows the functional block diagram of the 8-bit timer.
The 8-bit timer consists of an 8-bit counter (TMC), an 8-bit modulo register (TMM), a comparator which compares
the contents of the timer with the contents of the modulo register, and a selector which selects a count clock of the
8-bit timer.
Starting/stopping of the 8-bit timer and resetting of the 8-bit counter are controlled by TMEN (bit 3 of address 33H)
and TMRES (bit 2 of address 33H) of the register file. The count clock of the 8-bit timer is selected by TMCK1 (bit
1 of address 33H) and TMCK0 (bit 0 of address 33H) of the register file.
The contents of the 8-bit counter are read via the data buffer (DBF) by the GET instruction. The user cannot write
any value in the 8-bit counter. The user can set a value in the modulo register by the PUT instruction via the data
buffer (DBF).
The user cannot read the contents of the modulo register. As the 8-bit counter (TMC) and the modulo register
(TMM) use an identical address, the CPU accesses the 8-bit counter to read and the 8-bit modulo register to write.
When the current count value of the counter and the value of the modulo register coincide with each other, the
interrupt request flag (IRQTM: address 3EH, bit 0) is set, reflecting the output of the POD
1
/TMOUT pin.
TMOUT is initialized and outputs a high level when TMRES is set.
Caution Do not clear TMM to 0 (IRQTM cannot be set.)
