8-BIT TIMER (Cont’d)
9.2.6 Register Description
PRESCALER COUNTER REGISTER (PSCR)
Address: 0D2h - Read/Write
Reset Value: 0111 1111 (7Fh)
Bit 7 = PSCR7: Not used, always read as “0”.
Bits 6:0 = PSCR[6:0] Prescaler LSB.
TIMER COUNTER REGISTER (TCR)
Address: 0D3h - Read / Write
Reset Value: 1111 1111 (FFh)
Bits 7:0 = TCR[7:0] Timer counter bits.
TIMER STATUS CONTROL REGISTER (TSCR)
Address: 0D4h - Read/Write
Reset Value: 0000 0000 (00h)
Bit 7 = TMZ Timer Zero bit.
A low-to-high transition indicates that the timer
count register has underflowed. It means that the
TCR value has changed from 00h to FFh.
This bit must be cleared by user software.
0: Counter has not underflowed
1: Counter underflow occurred
Bit 6 = ETI Enable Timer Interrupt.
When set, enables the timer interrupt request. If
ETI=0 the timer interrupt is disabled. If ETI=1 and
TMZ=1 an interrupt request is generated.
0: Interrupt disabled (reset state)
1: Interrupt enabled
Bit 5 = TSCR5 Reserved, must be set.
Bit 4 = TSCR4 Reserved, must be cleared.
Bit 3 = PSI: Prescaler Initialize bit.
Used to initialize the prescaler and inhibit its count-
ing. When PSI=“0” the prescaler is set to 7Fh and
the counter is inhibited. When PSI=“1” the prescal-
er is enabled to count downwards. As long as
PSE=“1” both counter and prescaler are not run-
ning
0: Counting disabled
1: Counting enabled
Bits 1:0 = PS[2:0] Prescaler Mux. Select.
These bits select the division ratio of the prescaler
register.
