Specifications

Table 5-33 shows the HALT mode timing requirements, Table 5-34 shows the switching characteristics,

and Figure 5-19 shows the timing diagram for HALT mode.

(1)

For applications using X1/X2 for OSCCLK, the user must characterize their specific oscillator start-up time as it is dependent on

circuit/layout external to the device. See Table 5-17 for more information. For applications using INTOSC1 or INTOSC2 for OSCCLK,

see Section 5.9.3.5 for toscst. Oscillator start-up time does not apply to applications using a single-ended crystal on the X1 pin, as it is

powered externally to the device.

This value is based on the flash power-up time, which is a function of the SYSCLK frequency, flash wait states (RWAIT), and

FPAC1[PSLEEP]. For more information, see the Flash and OTP Power-Down Modes and Wakeup section of the TMS320F2837xD

Dual-Core Delfino Microcontrollers Technical Reference Manual. This value can be realized when SYSCLK is 200 MHz, RWAIT is 3,

and FPAC1[PSLEEP] is 0x860.
