Seconds Timer Interrupt (SECINT)

Reset Value

SFR F9h

WRT

SECINT6

SECINT5

SECINT4

SECINT3

SECINT2

SECINT1

SECINT0

7Fh

This system clock is divided by the value of the 16-bit register MSECH:MSECL. Then, that 1ms timer tick is divided by the

an interrupt which occurs from 100ms to 12.8 seconds. Reading this register will clear the Seconds Interrupt; however, AI

in EICON (SFR D8h) must also be cleared. This Interrupt can be monitored in the AIE or AIPOL registers.

WRT

Write Control. Determines whether to write the value immediately or wait until the current count is finished.

Read = 0.

bit 7

0 = Delay Write Operation. The SEC value is loaded when the current count expires.

1 = Write Immediately. The counter is loaded once the CPU completes the write operation.

SECINT6−0 Seconds Count. Normal operation would use 100ms as the clock interval.

bits 6−0 Seconds Interrupt = (1 + SEC) • (HMSEC + 1) • (MSEC + 1) • t

CLK

Milliseconds Timer Interrupt (MSINT)

Reset Value

SFR FAh

WRT

MSINT6

MSINT5

MSINT4

MSINT3

MSINT2

MSINT1

MSINT0

7Fh

The clock used for this timer is the 1ms clock, which results from dividing the system clock by the values in registers

MSECH:MSECL. Reading this register is necessary for clearing the interrupt; however, AI in EICON (SFR D8h) must also

be cleared.

WRT

Write Control. Determines whether to write the value immediately or wait until the current count is finished. Read = 0.

0 = Delay Write Operation. The MSINT value is loaded when the current count expires.

bit 7

1 = Write Immediately. The MSINT counter is loaded once the CPU completes the write operation.

MSINT6−0 Milliseconds Count. Normal operation would use 1ms as the clock interval.

bits 6−0 MS Interrupt Interval = (1 + MSINT) • (MSEC + 1) • t

CLK

One Microsecond Timer (USEC)

Reset Value

SFR FBh

FREQ5−0 Clock Frequency − 1. This value + 1 divides the system clock to create a 1µs Clock.

bits 5−0 USEC = CLK/(FREQ + 1). This clock is used to set Flash write time. See FTCON (SFR EFh).

MSECL7−0 One Millisecond Timer Low Byte. This value in combination with the next register is used to create a 1ms clock.

bits 7−0

1ms = (MSECH • 256 + MSECL + 1) • t

. This clock is used to set Flash erase time. See FTCON (SFR EFh).
