EM78P156N OTP ROM • RF can be cleared by instruction but cannot be set. • IOCF is the interrupt mask register. • Note that the result of reading RF is the "logic AND" of RF and IOCF. 8. R10 ~ R3F • All of these are 8-bit general-purpose registers.
EM78P156N OTP ROM • CONT register is both readable and writable. 3. IOC5 ~ IOC6 (I/O Port Control Register) • "1" put the relative I/O pin into high impedance, while "0" defines the relative I/O pin as output. • Only the lower 4 bits of IOC5 can be defined.
EM78P156N OTP ROM • Bit 5 (OD5) Control bit is used to enable the open-drain of P65 pin. • Bit 6 (OD6) Control bit is used to enable the open-drain of P66 pin. • Bit 7 (OD7) Control bit is used to enable the open-drain of P67 pin. • IOCC Register is both readable and writable.
EM78P156N OTP ROM Setting the ROC to "1" will enable the status of R-option pins (P50 ∼ P51) that are read by the controller. Clearing the ROC will di sable the R-option functi on. If the R-option function is selected, user must connect the P51 pin or/and P50 pin to VSS with a 430K Ω external resistor (Rex).
EM78P156N OTP ROM CLK=Fosc/4 is used if CLK bit is "1". If TCC signal source comes from exter nal clock input, TCC is increased by 1 at every falling edge or rising edge of TCC pin. • The watchdog timer is a free runni ng on-chip RC oscillato r .
EM78P156N OTP ROM R-option function is used, it is recommended that P50~ P51 are used as output pi ns. When R-option is in enable state, P50~P51 must be progra mmed as inpu t pins. Under R-option mode, the current/power consumption by Rex should be taken into the consideration to promote energy conservation.
