User code writes the required time interval to this register. When the 8-bit interval counter is equal to the

time interval value loaded in the INTVAL SFR, the TII bit (TIMECON.2) is set and generates an

interrupt if enabled.

SFR Address

A6H

Power-On Default

00H

Bit Addressable

Valid Value

0 to 255 decimal

HTHSEC

Hundredths Seconds Time Register

Function

This register is incremented in 1/128 second intervals once TCEN in TIMECON is active. The HTHSEC

SFR counts from 0 to 127 before rolling over to increment the SEC time register.

SFR Address

A2H

Power-On Default

00H

Bit Addressable

Valid Value

0 to 127 decimal

SEC

Seconds Time Register

Function

This register is incremented in 1-second intervals once TCEN in TIMECON is active. The SEC SFR

counts from 0 to 59 before rolling over to increment the MIN time register.

SFR Address

A3H

Power-On Default

00H

Bit Addressable

Valid Value

0 to 59 decimal

MIN

Minutes Time Register

Function

This register is incremented in 1-minute intervals once TCEN in TIMECON is active. The MIN SFR

counts from 0 to 59 before rolling over to increment the HOUR time register.

SFR Address

A4H

Power-On Default

00H

Bit Addressable

Valid Value

0 to 59 decimal

HOUR

Hours Time Register

Function

This register is incremented in 1-hour intervals once TCEN in TIMECON is active. The HOUR SFR

counts from 0 to 23 before rolling over to 0.

SFR Address
