STANDARD TIMER (Cont’d)
10.2.4 Register Description
COUNTER HIGH BYTE REGISTER (STH)
R240 - Read/Write
Register Page: 11
Reset value: 1111 1111 (FFh)
Bits 7:0 = ST.[15:8]: Counter High-Byte.
COUNTER LOW BYTE REGISTER (STL)
R241 - Read/Write
Register Page: 11
Reset value: 1111 1111 (FFh)
Bits 7:0 = ST.[7:0]: Counter Low Byte.
Writing to the STH and STL registers allows the
user to enter the standard timer constant from 1
(0000h) to 65536 (FFFFh). Reading these regis-
ters provides the counter's current value. Thus it is
possible to read the counter on-the-fly.
STANDARD TIMER PRESCALER REGISTER
(STP)
R242 - Read/Write
Register Page: 11
Reset value: 1111 1111 (FFh)
Bits 7:0 = STP.[7:0]: Prescaler.
The Prescaler value for the Standard Timer is pro-
grammed into this register. When reading the STP
register, the returned value corresponds to the
programmed data instead of the current data.
00h: No prescaler
01h: Divide by 2
FFh: Divide by 256

Reset value: 0001 0100 (14h)
Bit 7 = ST-SP: Start-Stop Bit.
This bit is set and cleared by software.
0: Stop counting
1: Start counting
Bit 6 = S-C: Single-Continuous Mode Select.
This bit is set and cleared by software.
0: Continuous Mode
1: Single Mode
Bits 5:4 = INMD[1:2]
Bit 3 = INEN
These 3 bits select the clock source.
Bit 2 = INTS: Interrupt Selection.
0: Standard Timer interrupt enabled
1: Standard Timer interrupt is disabled and the ex-
Bits 1:0 = OUTMD[1:2]: Output Mode Selection.
